Forty sandwich osteotomies in XXXX : a retrospective study.

@entity1 @entity132 @entity133 @entity3202
PURPOSE: The aim of the present retrospective study was to assess the suitability of segmental mandibular sandwich osteotomy combined with an interpositional autograft to meet the dimensional requirements of preimplant bone augmentation in cases of a severely @entity3202 mandible. @entity1 AND METHODS: A total of 27 consecutive @entity1 (6 @entity1 and 21 @entity1 ) were included in the present study. The amount of bone gain was calculated using digital volume tomography before surgery and 3 months after bone augmentation. RESULTS: The postoperative course was uneventful for 18 @entity1 . @entity132 were observed in 6 @entity1 , with complete recovery after 3 to 12 weeks. Dehiscence of soft tissue closure occurred in 3 @entity1 . The mean vertical gain was 3.41 mm (range 0.3 to 12). The mean horizontal gain was 3.08 mm (range 0.2 to 8.5). A total of 88 implants were placed in 40 surgical sites at 12 weeks after bone reconstruction. CONCLUSION: Segmental mandibular sandwich osteotomy is a suitable augmentation procedure in the mandible for the @entity133 and provides adequate height and transversal bone augmentation.
