Management of severely resorbed ridge using ridge splitting techniques with simultaneous implantation

الملخص EN

Atrophied premaxilla is considered one of the most problematic areas for rehabilitation with implant due to diminished ridge width and / or length.

Using of ridge splitting technique is one of the conservative surgical procedures that can be done under local anesthesia to increase the width of alveal ridge.

Materials &methods : Fourteen partially edentulous patients of both sexes were selected for this study with missing upper central or lateral incisors with proper bone height at the edentulous area (the average length was 13 mm) and resorbed bucco-lingual width (average bucco-lingual width was 3 : 4 mm) as indicated from ridge mapping and computed CT scan.

Patients were divided into 2 groups.

In Group one, ridge splitting was done using closed technique while in Group 2 ridge splitting was done using open technique, splitting was followed with simultaneous implantation in both group.

Result : Increasing of bone width were achieved in both group with ossoeintegration of installed implants, also the length and width of buccal bone in Group 1(closed technique) showed statistically significant bone loss in both vertical and buccolingual dimension in 4 cases and statistically non-significant change in the other cases.

While length and width of buccal bone in the Group 2 (open technique) showed statistically non-significant change along the follow up periods at 12 and 18 months.

Conclusion : Open technique of ridge splitting is simple technique that can improve ridge width with simultaneous implantation without postoperative complication.
