Introdução: A reabilitação parcial ou total de pacientes edêntulos com implantes
dentários está relacionado com uma alta taxa de sucesso na reabilitação oral.
Fatores que podem alterar a perda de volume ósseo são as doenças sistêmicas,
extração dentária, tumores, traumas e doenças periodontais e, que irá limitar o
posicionamento dos implantes nas áreas edêntulas alveolares.
Objetivo: O objetivo deste estudo é avaliar os resultados clínicos e radiográficos
na colocação implantes dentários em cristas edêntulas com pequenos defeitos
horizontais alveolares, tratadas com uma membrana de colagénio com
propriedades ossificantes para o aumento do volume alveolar perdido.
Materiais e Métodos: Foram estudados pacientes tratados com implantes
dentários em simultâneo com colocação de uma membrana de colagénio OSSIX
Volumax em locais edêntulos mandibulares, diagnosticados com um defeito
ósseo horizontal não crítico para a colocação dos mesmos. Os dados foram
recolhidos em três momentos: T0 (baseline ou momento da colocação dos
implantes), T1 (6 meses após a colocação dos implantes) e T2 ( 12 meses após a
colocação dos implantes. Para a medição das alterações volumétricas a nível
vestibular através da sobreposição de impressões digitais, foram estudadas as
variáveis Buccal Volume variation (BVv) e Mean Buccal variation (MBV). Em
termos de alterações ósseas marginais foram caracterizadas em duas variáveis
mesial marginal bone changes (mMBC) e distal marginal bone changes (dMBC).
Resultados: A utilização da membrana de colagénio reticulada mostrou um
aumento médio de 28.70+-15.81% em termos de alterações volumétricas (BVv)
aos 12 meses , 0.81+-0.50mm nas medidas lineares da superfície alveolar (MBV) de
T0 para T2 (12 meses) e uma perda óssea de -0.71mm nos implantes anteriores e
-0.29mm nos implantes posteriores em termos de alterações ósseas marginais. Os
resultados para o MBC não foram estatisticamente significativos.Conclusão:
Existe uma forte associação entre a utilização de uma membrana de colagénio
ossificante e um ganho de volume bucal, em relação à manutenção do osso marginal
não se verificou uma melhoria em relação à literatura.
Introduction: The partial or total rehabilitation of edentulous patients with dental implants is related to a high success rate in oral rehabilitation. Factors that can alter the loss of bone volume are systemic diseases, tooth extraction, tumors, trauma, and periodontal diseases, which will limit implant positioning in the alveolar edentulous areas. Objective: The aim of this study is to evaluate the clinical and radiographic results of placing dental implants in edentulous ridges with small horizontal alveolar defects, treated with a collagen membrane with ossifying properties to increase the lost alveolar volume. Materials and Methods: Patients treated with dental implants simultaneously with placement of an OSSIX collagen membrane Volumax in mandibular edentulous sites, diagnosed with a non-critical horizontal bone defect for implant placement, were studied. Data were collected at three time points: T0 (baseline or time of implant placement), T1 (6 months after implant placement) and T2 ( 12 months after implant placement. The Buccal Volume variation (BVv) and Mean Buccal variation (MBV) variables were studied for measuring volumetric changes at the buccal level by superimposing fingerprints. In terms of marginal bone changes were characterized in two variables mesial marginal bone changes (mMBC) and distal marginal bone changes (dMBC). Results: The use of the cross-linked collagenium membrane showed an average increase of 28.70+-15.81% in terms of volumetric changes (BVv) at 12 months, 0.81+-0.50 mm in the alveolar surface linear measurements (MBV) from T0 to T2 (12 months) and a bone loss of -0.71 mm in the anterior implants and -0.29 mm in the posterior implants in terms of marginal bone changes. The results for the MBC were not statistically significant. Conclusion: There is a strong association between the use of an ossifying collagen membrane and a gain of buccal volume , in relation to the maintenance of marginal bone there was not an improvement comparing with the literature.
