Alveolar Ridge Splitting Versus Autogenous Onlay Bone Grafting

Abstract

When reconstructing vertically sufficient but horizontally insufficient alveolar ridges, ridge splitting technique could shorten the treatment period, decrease postoperative swelling and pain, eliminate the need for a second surgical site, reduce the treatment cost, and ease the patient cooperation to the surgery.

Comparison of alveolar ridge splitting and autogenous onlay bone grafting to enable implant placement in patients with atrophic jaw bones

“…The complication rate is low (6.8%), the most common being a buccal bone fracture. Altiparmak et al 7 also reported the buccal bone fracture as the most commonly seen complication, followed by temporary graft exposure. We observed several intraoperative and postoperative complications, all of which were managed uneventfully.…”

“…However, it is important to note that there should be a layer of cancellous bone between the cortical plates to enable splitting. 7 - 9 In a systematic review on ridge augmentation techniques, Milinkovic and Cordaro 15 stated that the mean initial horizontal thickness where autogenous block grafts were used was 3.2 mm (range, 2.5 to 3.89 mm). The linear bone gain was 4.3 mm (range 2.7 to 5.0 mm) after a healing time of approximately 5.6 months.…”

“…There needs to be a minimal cortical bone thickness of 3 mm together with trabecular bone between the cortical layers to perform ARS. 7 - 9 There are some advantages of ARS compared with autogenous onlay bone grafting (AOBG), including fewer surgical complications and lower morbidity, as well as a shorter healing time. 7 - 9 Various surgical procedures have been described to augment deficit bone.…”

“… 7 - 9 There are some advantages of ARS compared with autogenous onlay bone grafting (AOBG), including fewer surgical complications and lower morbidity, as well as a shorter healing time. 7 - 9 Various surgical procedures have been described to augment deficit bone. Most research discusses the outcomes of these techniques, but there is still controversy in selecting the preferred technique because of a lack of comparative studies.…”

Flapless Ridge Splitting Technique with Platelet Rich Fibrin for Immediate Implant Placement in Atrophic Alveolar Ridge

“…Various techniques were suggested for augmentation of the thin alveolar ridge such as guided bone regeneration (GBR), onlay bone grafting (OBG), alveolar distraction osteogenesis (ADO), and alveolar ridge-split (ARS) techniques. Considering for alveolar bone augmentation, relevant and better results for implant survival and stability were reported in the literature for ridge splitting technique (4)(5)(6)(7)(8) .…”
