Retrospective cross-sectional study of the lingual concavity of the mandible using cone-beam computed tomography
Introduction: The curved shape of the mandible, the lingual concavity and the inferior alveolar nerve are factors that make implant placement difficult in the posterior mandibular region. The knowledge of these structures can help avoid surgical complications. Objective: The aim of this study was to analyze and correlate anatomical features of partially edentulous posterior mandibles using cone-beam computed tomography images of the hemimandibles at 5, 10, and 15mm posterior to the mental foramen. Material and method: A total of 39 hemimandible specimens from 12 male and 27 female patients were used. The factors analyzed were bone thickness 2mm above the inferior alveolar canal (Thickness A), bone thickness 2mm below the alveolar crest (Thickness B), angulation and depth of the lingual concavity, mandibular height, and mandibular shape (U, C, or P). Result: Thickness A (P = 0.5355), thickness B (P = 0.2353), concavity angle (P = 0.9806) and depth (P =0.4977) were similar in both sexes. Height showed higher and statistically significant values in male population (P = 0.0099). The C shape was the most frequent (55%), followed by U (25.0%) and P (20.0%). Conclusion: The U-shaped mandibular morphology was observed in 25% of the sample. Posterior mandibular height was greater in males. The thickness and depth of the posterior mandibular areas did not vary according to sex.

REMOÇÃO DE IMPLANTES DENTÁRIOS E FECHAMENTO DE COMUNICAÇÃO BUCOSINUSAL COM RETALHO PEDICULADO DO CORPO ADIPOSO BUCAL: RELATO DE CASO.
Introdução: A comunicação bucosinusal é uma complicação que pode ocorrer após procedimentos odontológicos na região posterior da maxila, incluindo exodontias e instalação de implantes dentários. Quando associada à projeção de implantes para o interior do seio maxilar, pode favorecer processos inflamatórios e infecciosos, exigindo intervenção cirúrgica. Nesse contexto, o corpo adiposo bucal representa uma alternativa para o fechamento desses defeitos, devido à sua adequada vascularização e facilidade de mobilização. Objetivo: O presente trabalho relata um caso clínico de remoção de implantes dentários associados à comunicação bucosinusal, com manejo da cavidade sinusal e fechamento por meio de retalho pediculado do corpo adiposo bucal. Relato de caso: Paciente do sexo masculino, 65 anos, apresentou passagem de líquidos da cavidade oral para a nasal e episódios recorrentes de sinusite. Os exames clínicos e imaginológicos evidenciaram comunicação bucosinusal associada a dois implantes, cuja maior extensão encontrava-se projetada para o interior do seio maxilar esquerdo, além de alterações compatíveis com sinusite maxilar de origem odontogênica. O tratamento consistiu na remoção dos implantes por torque reverso, seguida de curetagem e irrigação sinusal. Posteriormente, realizou-se o fechamento da comunicação com retalho pediculado do corpo adiposo bucal. O acompanhamento pós-operatório demonstrou evolução favorável, com adequada cicatrização e ausência de deiscência ou sinais clínicos de infecção. Conclusão: Conclui-se que a associação entre remoção dos implantes, abordagem sinusal e utilização do corpo adiposo bucal demonstrou ser uma alternativa viável para o tratamento dessa complicação, proporcionando resolução da sintomatologia e adequada cicatrização dos tecidos.

Evaluation of the Osteoconductive Capacity of Micro-Hydroxyapatite and Nano-Hydroxyapatite Associated with Beta-Tricalcium Phosphate: Experimental Study in Critical Calvarial Defects in Rats
Among the biomaterials used in grafting techniques for bone rehabilitation and subsequent dental implant placement, biphasic ceramics have emerged as promising alternatives, prompting investigations into their structural and biological properties. The objective of this study was to evaluate bone repair in critical-size calvarial defects in rats using two particulate biphasic ceramics composed of micro- or nano-hydroxyapatite associated with βtricalcium phosphate in different proportions. Seventy-two Wistar rats were used, distributed into four groups: blood clot (BC); GenPhos® 70/30 (GP), containing micro-HA; Blue Bone® 80/20 (BB), containing nano-HA; and Bio-Oss® (BO). In each rat, a critical defect was created in the calvaria, filled according to the group and covered with a collagen membrane. The animals were euthanized at 7, 14, and 28 days. Histomorphometric analysis was performed, quantifying newly formed bone, biomaterial, and connective tissue, in addition to microcomputed tomography (Micro-CT), adopting p < 0.05, and qualitative histological analysis. In the Micro-CT analysis, no significant differences in bone volume were observed among the groups, although the BB group exhibited a more pronounced trabecular microarchitecture. Histomorphometrically, all biomaterial groups were superior to BC (p < 0.001). The BB group showed similar mean new bone formation (45.03%) compared to the BO group (46.62%), at 28 days, with no statistically significant difference, exhibiting an intraparticular osteoconduction pattern. The GP group demonstrated greater resorption dynamics (17.22%), whereas BO remained the most stable (44.22%). The BC group showed the highest connective tissue persistence (68.07%). It is concluded that the biphasic ceramics and the xenogeneic biomaterial promoted defect closure, with nano-hydroxyapatite (BB) demonstrating great qualitative performance in trabecular organization and initial vascularization, indicating that the nanometric scale and the bioactivity of β-TCP favor a dynamic tissue replacement in critical defects.

Distinct healing dynamics associated with xenograft selection in guided bone regeneration
Guided bone regeneration relies on biomaterials that support bone formation while modulating the healing environment; however, materials with similar indications may exhibit different biological behaviors over time. This study compared the performance of two bovine-derived bone substitutes containing collagen using a rat calvarial critical-size defect model. Fifty-four Wistar rats were allocated to three groups: blood clot (control), Bio-Oss Collagen ® , and Extra Graft XG13 ® . Standardized 5-mm defects were created and treated under guided bone regeneration conditions using a resorbable collagen membrane. Animals were euthanized at 7, 14, and 28 days. Mineralized tissue formation and microarchitecture were assessed by micro-CT, while histological, histomorphometric, inflammatory, angiogenic, and collagen organization analyses were performed to characterize the healing process. Both biomaterials supported tissue formation within the defect compared to the control. Extra Graft XG13 ® was associated with higher mineralized tissue volume and volume fraction at 14 and 28 days, with more favorable micro-CT-derived microarchitectural parameters and reduced porosity. Early inflammatory and angiogenic responses were comparable between biomaterials, yet defects treated with Extra Graft XG13 ® exhibited greater new bone formation over time. A reduction in mineralized tissue volume from 14 to 28 days in this group, accompanied by increased collagen organization, may suggest a possible transition toward remodeling; however, this interpretation should be considered with caution due to the absence of direct remodeling markers. In contrast, Bio-Oss Collagen ® showed a more gradual pattern of tissue formation and delayed collagen maturation. Overall, Extra Graft XG13 ® was associated with greater mineralized tissue formation and a higher proportion of organized collagen fibers at later time points, indicating differences in the progression of mineralized tissue formation and matrix organization over time compared to Bio-Oss Collagen ® . These findings should be interpreted within the limitations of the experimental model.

Estudo microscópico do vidro bioativo associado à membrana biológica absorvível de pericárdio bovino para regeneração óssea em defeitos ósseos críticos de calvárias de ratos
Objetivo: avaliar a efetividade do uso de enxerto de vidro bioativo (ActiveBone) associado à membrana biológica óssea absorvível de pericárdio bovino (Techgraft) na regeneração óssea de calvárias de ratos. Material e métodos: foram utilizados 20 ratos Wistar (Rattus Novergicus Albinus) machos com peso entre 300 g e 400 g, com 15 semanas de vida. Os animais foram divididos aleatoriamente em dois grupos – Grupo 1 (controle): foi realizado o defeito ósseo na calota craniana do animal e instalada a membrana biológica absorvível de pericárdio bovino. Na sequência, foi realizada sutura com pontos interrompidos; Grupo 2 (experimental): o defeito ósseo recebeu enxerto de vidro bioativo e foi coberto com membrana biológica absorvível de pericárdio bovino, com posterior sutura. Após 30 e 60 dias, cinco animais de cada grupo foram eutanasiados, formando os subgrupos: controle 30 dias; controle 60 dias; experimental 30 dias; e experimental 60 dias. As calvárias foram removidas e preservadas. Após a microtomia, as lâminas foram coradas pela hematoxilina e eosina, e realizadas as análises microscópica e histomorfométrica. Resultados: após 30 e 60 dias, o defeito ósseo provocado nos animais apresentou neoformação óssea por toda a sua extensão, tanto no grupo-controle quanto no grupo experimental. Todavia, não houve diferenças estatisticamente significativas entre os grupos. Conclusão: os resultados microscópicos e histomorfométricos permitiram concluir que o vidro bioativo associado à membrana biológica absorvível de pericárdio bovino pode ser considerado um material osteocondutivo, visto que foi efetivo no reparo ósseo de defeitos críticos de calvária de ratos. Palavras-chave – Regeneração óssea; Materiais biocompatíveis; Substitutos ósseos.

CONSERVATIVE APPROACH TO THE MANAGEMENT OF EXTENSIVE ODONTOGENIC KERATOCYST IN THE MANDIBLE WITH RISK OF PATHOLOGICAL FRACTURE
The present clinical case report aims to describe the conservative surgical management of an extensive odontogenic keratocyst (OK) in the posterior mandibular region, associated with an impacted tooth and near the mandibular canal. A 21-year-old female patient presented with pain and paresthesia in the left mandibular area. Panoramic radiography and cone-beam computed tomography (CBCT) revealed a well-defined, multilocular radiolucent lesion involving the impacted tooth 38 and overlapping the mandibular canal. Initial treatment consisted of an incisional biopsy and cyst decompression, aiming to reduce lesion volume and minimize neurosensory risk. Clinical and radiographic follow-up demonstrated progressive reduction of the cystic cavity and thickening of the cortical bone, while histopathological examination confirmed the diagnosis of odontogenic keratocyst. The patient progressed without pain and with stable paresthesia, maintaining adequate hygiene and good adaptation to the decompression device. The two-stage approach proved effective for initial lesion control and for safely planning definitive treatment, reinforcing that in large lesions located near the inferior alveolar nerve, decompression followed by definitive therapy represents a conservative, predictable, and safe strategy.

Avaliação da estabilidade primária, torque de inserção e de remoção dos implantes Veloce®: estudo in vitro
Objetivos: avaliar a estabilidade primária dos implantes Veloce®. Material e Métodos: Foram instalados 40 implantes de hexágono externo (3,75mm x 11,5mm) em blocos de poliuretano simulando os ossos tipos I, II, III e IV (10 implantes para cada tipo de bloco), medindo-se a análise de frequência de ressonância (Osstell), torque de inserção (TI) e torque de remoção (TR). Resultados: Os maiores valores de TI foram observados nos blocos tipo I e II quando comparados entre si aos blocos tipos III e IV (p < 0,0001). Contudo, não foram observadas diferenças quando comparado TI dos blocos tipo III e IV. De modo semelhante, os valores de TR foram maiores para os blocos tipo I e II, com diferença estatística, comparados aos blocos tipos III e IV (p = 0,0003). Não foram observadas diferenças quando comparado o TR dos blocos tipo I e II e entre III e IV. No que se refere aos dados obtidos pelo teste de frequência de ressonância, diferenças estatísticas foram observadas apenas quando comparado o bloco tipo I com os blocos tipos III. Não foram observadas diferenças quando comparado o teste da frequência de ressonância dos blocos tipo I e II, entre II e III, entre II e IV e entre III e IV. Conclusão: De acordo com a metodologia empregada e com os resultados obtidos neste estudo “in vitro”, a estabilidade primária dos implantes Veloce® foi diretamente influenciada pelas diferentes densidades dos blocos de poliuretano.

Análise histológica e morfométrica da reação tecidual no uso de membrana de PTFe em calvárias de ratos
O objetivo do presente estudo foi avaliar histológica e morfometricamente, a reação tecidual, na utilização de membrana não-reabsorvível, produzida em politetrafluoretileno com reforço de titânio, como uma barreira celular de exclusão, em defeitos ósseos críticos, provocados em calvária de ratos. Para análise, foram utilizados 20 ratos machos Wistar (Rattus norvegicus albinus), com peso variando entre 300 a 400g. Os defeitos foram criados com uma broca trefina de 5 mm, no centro de osso parietal. Em 10 ratos, grupo experimental, o defeito foi coberto com a membrana Cytoplast Ti250 Titanium-Reinforced, os outros 10 animais do grupo controle não tiveram o defeito protegido pela membrana. Cinco animais de cada grupo sofreram eutanasia com 30 dias e os outros cinco restantes, com 60 dias. Após análise histométrica mostrou uma média de 59% de neoformação óssea no grupo experimental 30 dias e de 70% de neoformação óssea no grupo experimental 60 dias, demonstrando a eficiência da membrana de politetrafluoretileno como barreira de exclusão na regeneração óssea guiada.

Clinical Resolution of Recurrent Sinusitis after Removal of Surgical Drill in the Maxillary Sinus: Case Report
This report describes the clinical resolution of recurrent sinusitis after removing a surgical drill from the maxillary sinus (MS) using the modified Caldwell-Luc technique. A 52-year-old male presented at the Oral and Maxillofacial Surgery Clinic of Araçatuba School of Dentistry - UNESP, complaining of recurrent headaches, sinusitis, and facial edema for one year, following the extraction of tooth #26 and subsequent oroantral communication. Physical examination revealed edema in the left midface, effacement of the fornix fundus, erythema, and an active fistula near tooth #23. A panoramic radiograph showed a radiopaque foreign body in the left MS. Cone beam computed tomography (CBCT) revealed hyperdense material resembling a surgical drill, bone fenestration, and residual roots. The MS was accessed using the modified Caldwell-Luc technique, expanding the previous bone fenestration to remove the drill, perform curettage, and irrigate the sinus. The fistula was excised, and residual roots of tooth #24 were extracted. The patient remained under clinical and radiographic follow-up with no complications. Complementary imaging is crucial for diagnosis and surgical planning, and the modified Caldwell-Luc technique is effective for foreign body removal in the MS, offering a low-cost solution, complete sinus cleansing, and prevention of oroantral fistula recurrence.

Clinical Resolution of Recurrent Sinusitis after Removal of Surgical Drill in the Maxillary Sinus: Case Report
This report describes the clinical resolution of recurrent sinusitis after removing a surgical drill from the maxillary sinus (MS) using the modified Caldwell-Luc technique. A 52-year-old male presented at the Oral and Maxillofacial Surgery Clinic of Araçatuba School of Dentistry - UNESP, complaining of recurrent headaches, sinusitis, and facial edema for one year, following the extraction of tooth #26 and subsequent oroantral communication. Physical examination revealed edema in the left midface, effacement of the fornix fundus, erythema, and an active fistula near tooth #23. A panoramic radiograph showed a radiopaque foreign body in the left MS. Cone beam computed tomography (CBCT) revealed hyperdense material resembling a surgical drill, bone fenestration, and residual roots. The MS was accessed using the modified Caldwell-Luc technique, expanding the previous bone fenestration to remove the drill, perform curettage, and irrigate the sinus. The fistula was excised, and residual roots of tooth #24 were extracted. The patient remained under clinical and radiographic follow-up with no complications. Complementary imaging is crucial for diagnosis and surgical planning, and the modified Caldwell-Luc technique is effective for foreign body removal in the MS, offering a low-cost solution, complete sinus cleansing, and prevention of oroantral fistula recurrence.
