Abstract

Alveolar kemik split tekniği, hemen implant yerleştirilmesi ile birlikte, genellikle alveolar kemik genişliğinin eksikliğini gidermek ve tedavi süresini önemli ölçüde kısaltmak için yapılır. Mandibulada daha yüksek kırık riski ve primer implant stabilitesi eksikliği vardır. Bunun için iki aşamalı teknik tavsiye edilir. Bu çalışma, mandibulanın posterior bölgesindeki iki aşamalı alveolar kemik split tekniğinin klinik sonuçlarını raporlamaktadır. Posterior mandibular bölgede, dar dişsiz alveoler kemiğe sahip toplam 12 hasta çalışmaya dahil edildi ve alveolar kemiğin genişliğini arttırmak için iki aşamalı alveolar kemik split tekniği uygulandı. Ameliyattan 4 ay sonra genişletilmiş alveolar kemiklere 15 dental implant yerleştirildi. Alveolar kemik genişliği, cerrahi komplikasyonlar ve dental implantların sağkalım oranları değerlendirildi. Alveolar kemiğin genişliğindeki ortalama kemik kazancı şuydu: ameliyattan sonra 2.8 mm (SD: 0.53) (aralık, 2.1 - 3.6 mm) ve ameliyattan 4 ay sonra 2.22 mm (SD: 0.23) (aralık, 1.9 - 2.6 mm). Ayrıca bir komplikasyon (yara dehisens) kaydedildi. 6 aylık fonksiyonel yüklemeden sonra implantların sağkalım oranı% 93.3 olarak tespit edilmiştir. Genişleyen alanların % 84.61'i yeterli genişlik sağlamada başarılı olmuştur. Bu teknik, uygun vakalar seçildiğinde tatmin edici sonuçlarla güvenli bir teknik olarak kabul edilebilir.

Expansion the Narrow Posterior Mandibular Alveolar Ridge Using Two-Stage Ridge Splitting Technique

Abstract

Alveolar ridge splitting technique with immediate implant placement is usually performed to overcome the deficiency of the alveolar bone width and significantly shortens the treatment time. In the mandible there is a higher risk of malfractures and a lack of initial stability for the implants, so the two-stage technique is recommended. The present study reports the clinical results of the two-stage ridge technique in the posterior region of the mandible. A total of 12 patients with an edentulous narrow alveolar bone ridge in the posterior mandibular region were included in the present study, Two-stage ridge splitting technique was applied to increase the width of alveolar bone. After 4 months of surgery, 15 dental implants were inserted in the expanded ridges. The alveolar bone width, complications of the surgery, and survival rate of dental implants were evaluated. The mean bone gain in the width of the alveolar bone was: after surgery 2.8 mm (SD: 0.53) (range, 2.1 – 3.6 mm), and after 4 months of surgery 2.22 mm (SD: 0.23) (range, 1.9 – 2.6 mm). One case of wound dehiscence was recorded. The survival rate of implants was 93.3 % after 6 months of functional loading. 84.61% of the expanded areas were successful in providing an adequate width. This technique can be considered a safe procedure with satisfactory results if appropriate cases selected.
