Gingival recession is an oral health problem that affects a large part of the population. Several treatments are suggested in the current literature; among them is the use of buccal fat pad grafting. The objective of this case report is to describe the treatment of a Miller Class I gingival recession using a nonpedicled buccal fat pad graft immediately after performing the surgery for buccal fat pad removal (bichectomy technique). First, bilateral surgical removal of the buccal fat pad was performed with the main objective of eliminating oral mucosa biting. The recipient site was prepared to receive a portion of the fat pad that was cut and macerated in a size that was sufficient to cover the recession. The patient was followed up at 15, 30, 60, and 365 days postsurgery, and the results showed an elimination of the oral mucosa biting and complete coverage of the gingival recession. It was concluded that the nonpedicled buccal fat pad graft is another option for the treatment of Miller Class I recessions.
A instalação imediata de implantes em molares constitui um desafio, pois a quantidade óssea remanescente após a exodontia é restrita. Objetivo: Mostrar como a odontosecção seguida da fresagem para instalação do implante dentário e posterior remoção das raízes em dentes molares ajuda a preservar o septo ósseo. Relato de caso: Paciente com dente 36 condenado por fratura foi submetida ao procedimento cirúrgico de exodontia com odontosecção e instalação de implante imediato na região do septo ósseo interradicular, seguida de regeneração óssea guiada com biomaterial sintético, membrana bovina e com reabilitação protética provisória. Após período de osseointegração foi instalada a prótese definitiva. Conclusão: A técnica da odontosecção seguida da fresagem para instalação do implante dentário e posterior remoção das raízes em dentes molares ajuda a preservar o septo ósseo inter-radicular e favorece a instalação do implante dentário em uma posição mais centralizada. A técnica, associada a regeneração óssea guiada, minimiza a remodelação da crista óssea alveolar.
Novel biomaterials capable of accelerating the healing process of skeletal tissues are urgently needed in dentistry. The present in vivo study assessed the osteoconductive and osteoinductive properties of experimental biphasic bioceramics (HA-TCP) modified or not by a nacre extract (marine organic extract, MOE) in a sheep model. Fabrication of MOE involved mixing ground nacre (0.05 g, particle sizes < 0.1 mm) with glacial ethanoic acid (5 mL, pH 7) for 72 hours using external magnetic stirring (25°C). Nonreactive carriers (sterile polythene tubes; 3/animal, radius: 2.5 mm, length: 10.0 mm) pertaining to the control (empty) or experimental groups (HA-TCP or MOE-modified HA-TCP) were implanted intramuscularly into the abdominal segment of the torso in sheep (n = 8, age: 2 years, weight: 45 kg). Euthanization of animals was performed at 3 and 6 months after surgery. Tissues harvested were subjected to macroscopic and radiographic assessments. Specimens were then stained for histological analysis. Both control and experimental animals were capable of inducing the neoformation of fibrous connective tissue at both time points where superior amounts of tissue formation and mineralization were detected for experimental groups (unaltered (at 3 and 6 mos) and MOE-modified HA-TCP (at 3 mos)). Histological results, however, revealed that mature bone formation was only observed for specimens fabricated with MOE-modified HA-TCP in a time-dependent manner. The present study has successfully demonstrated the in vivo utility of experimental biphasic bioceramics modified by MOE in an ectopic grafting sheep model. Promising osteoconductive and osteoinductive properties must be further developed and confirmed by subsequent research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
