Deproteinized bovine bone derived with collagen improves soft and bone tissue outcomes in flapless immediate implant approach and immediate provisionalization: a randomized clinical trial.

OBJECTIVES: This study aimed at evaluating soft and hard tissue dimensions after immediate implant placement and immediate temporization with or without alveolar preservation at the maxillary anterior region. MATERIALS AND METHODS: Twenty-two patients needing maxillary incisor extraction and with the possibility of immediate implant placement were randomly assigned to the following groups: test (n = 11): immediate implant placement + deproteinized bovine bone derived with collagen inserted into the alveolus or control (n = 11): immediate implant placement without biomaterial. All soft tissue measurements were evaluated at baseline, 3 months, and 6 months after implant therapy. Cone beam tomography was performed at baseline and at 6 months after implant placement to evaluate hard tissue dimension. RESULTS: The test group presented higher height of soft tissue at mesiobuccal and distobuccal sites at 3 months and 6 months when compared to the control group (p < 0.05). Regarding the bone tissue, the test group showed higher buccolingual ridge dimension at 6 months when compared to the control group (p < 0.05). CONCLUSIONS: It can be concluded that the use of deproteinized bovine bone derived with collagen together with immediate dental implants results in better soft and bone tissue outcomes than immediate implants alone. CLINICAL RELEVANCE: The use of deproteinized bovine bone derived with collagen may enhance the results regarding soft and bone tissue in combination with immediate implant and temporization.

Defeito ósseo de Stafne û relato de dois casos / Stafne bone defect û report of two cases

A cavidade óssea de Stafne, também conhecida como pseudocisto de Stafne ou cavidade óssea idiopática, tem gerado muitos conflitos nos diagnósticos entre os profissionais de Odontologia. A lesão supracitada faz parte de um conjunto de lesões radiolúcidas e assintomáticas descritas por Edward Stanfe (1942) e está topograficamente localizada entre o ângulo mandibular e o primeiro molar inferior, abaixo do canal alveolar inferior, sendo denominada de depressão óssea mandibular lingual posterior. O tratamento consiste apenas em acompanhamento radiográfico e tomografia...

The bone cavity Stafne, also known as pseudocyst of Stafne or idiopathic bone cavity, has generated many conflicts regarding diagnosis among dental professionals. The aforementioned lesion is part of a set of radiolucent and asymptomatic lesions described by Edward Stanfe in 1942 and is topographically located between the mandibular angle and the lower first molar, under the inferior alveolar channel, and it is called posterior lingual mandibular bone depression. Treatment consists only of radiographic follow-up and cone-beam tomography...

Abordagem integrada para tratamento de lesão pigmentada e coroas clínicas curtas / An integrated opprooch to treotment of a pigmented lesion ond short clinicol crowns

Lesões pigmentadas são geralmente encontradas na cavidade oral e podem estar relacionadas a lesões malignas, e portanto sua remoção pode ser indicada. Neste sentido, cuidados devem ser tomados no planejamento cirúrgico para remoção da lesão, principalmente das que acometem a região anterior superior, para que este procedimento possibilite o diagnóstico correto da condição, preferencialmente, sem comprometer a estética do sorriso. O objetivo deste artigo é descrever um caso clínico de lesão pigmentada enegrecida, localizada na papila interdental dos incisivos centrais superiores. Devido a queixa estética da paciente e tendo como objetivo principalmente o correto diagnóstico desta condição, foi realizado procedimento cirúrgico para remoção desta lesão. Juntamente com a biópsia excisional, foi realizado aumento das coroas clínicas dos dentes anteríores superiores visando o equilíbrio do contorno gengiva I. Baseado no aspecto clínico e exame histopatológico, a lesão foi diagnosticada como mácula melânica, afastando qualquer quadro de malignidade, além disso, o procedimento cirúrgico realizado propiciou bom resultado estético.

Pigmented lesions are generally found in the oral cavity and may be related to maglignant lesions, although this association is rare. In this sense, care must be taken in surgical planning for removal of the lesion, particularly lesions that affect the maxillary anterior region, 50 that this procedure enables the correct diagnosis of the condition, preferably without compromising the esthetics of the smile. The aim of this article is to describe a clinical case of a blackened pigmented lesion located in the interdental papilla of the maxillary central incisors. Due to the patient's complaint about esthetics and mainly with the purpose of correctly diagnosing this condition, a surgical procedure was performed to remove the lesion. Together with the exisional biopsy, augmentation of the clinical crowns of the maxillary anterior teeth was performed in order to achieve balance of the gingival contour. Based on the clinical aspect and histopatho- logic exam, the lesion was diagnosed as a melanotic macule, removing any question of it being a malignant condition, and in addition, the surgical procedure enabled the safe removal of the lesion and provided a good esthetic result.
