Horizontal alveolar distraction of the narrow maxillary ridge for implant placement

AIM: The aim of the present prospective study was to evaluate the long-term outcome of implants placed simultaneously with guided bone regeneration (GBR) using resorbable and non-resorbable membranes. MATERIALS AND METHODS: The original study population consisted of 72 patients receiving a total of 265 implants. In all GBR-treated sites, demineralized bovine bone mineral (DBBM) was used in combination either with a collagen (CM) or an Expanded polytetrafluoroethylene (e-PTFE) membrane. A total of 112 implants was treated with CM, 41 implants were treated with e-PTFE membranes, and 112 served as a control group because implants were entirely surrounded by bone and did not need any GBR procedures. Clinical and radiographic analyses were performed after a period of 12-14 years. RESULTS: The median follow-up time was 12.5 years (range 12-14 years). A total of 58 patients participated in the present investigation, corresponding to 80.5% of the original study population. The cumulative implant survival rate at the follow-up examination was 93.2%. For the control group the cumulative survival rate was 94.6%, for the CM 91.9%, and for the e-PTFE 92.6%. Differences among the groups were not statistically significant. The radiographically determined marginal bone level (MBL) amounted to: CM 2.36 mm (SD), e-PTFE 2.4 mm (SD), control 2.53 mm (SD). There is no evidence (P < 0.2) that the slope of bone level over time is different for the three treatment groups. CONCLUSION: It is concluded that implants placed simultaneously with GBR procedures using resorbable or non-resorbable membranes reveal a high survival rate ranging from 91.9% to 92.6%, therefore it is considered to be a safe and predictable therapy.

Dental implants are the treatment of choice for the replacement of missing teeth nowadays.But placement of implants in the alveolar bone remains a challenge for most of the clinicians because of the resorption of the residual ridge resulting in insufficient bone volume in one or more dimensions. Various surgical techniques to augment the thin ridges not only increases the morbidity but also results in increase of the expenditure involved as well as time taken. All these factors act as deterrents for the acceptance of the treatment plan by the patient. Need of the hour is to review the various bone manipulation techniques developed over the years and use a suitable conservative technique.

“…The advantages of DO over bone grafts or GBR include the lack of the need for a donor site and simultaneous lengthening of the surrounding soft tissues. Horizontal DO for correcting a narrow alveolar ridge has also been reported (Laster et al 2005;Laster et al, 2011;Gaggl et al 2005;Chiapasco et al 2006b;Garcia-Garcia et al 2004;Oda et al 2004;Takahashi et al 2004;Watzak et al 2006). However, most of those reports were experimental studies or case reports/series about the technique; there are few reports on the long-term results of horizontal DO.…”
