Outcome Measures

Primary Outcomes (2)

Clinical measurements
Clinical measurements were carried out using Williams probe (Karl Hammacher GmbH, Solingen, Germany) prior to ridge splitting surgery after the full thickness flap elevation, to evaluate the width of the alveolar ridge (preoperative measurement) and after a 3-month healing period, before implant placement (postoperative measurement). The width of the alveolar ridges was measured at 3, 10, and 15 mm from the reference point, which was the distal marginal bone of the last tooth of the quadrant. To ensure that preoperative and postoperative measurement sites corresponded, we placed the tip of the Williams probe on the reference point described and the markings of the probe to the highest ridge of the lingual cortical.

Autograft

EXPERIMENTAL

The filler used in ridge splitting is autologous bone block harvested from mandible * Interventions: * Procedure: ridge splitting * Procedure: bone core biopsy * Device: dental implant placement * Measurement: clinical measurement with Williams probe * Micro-CT analysis * Histomorphometric measurements

Procedure: Alveolar ridge splittingDevice: Creating osteotomies with piezoelectric device

Interventions

Alveolar ridge splittingProcedure

Patients with Kennedy Class I. and II. mandibles with insufficient bone width were included in this study. Ridge splitting was carried out with the use of a piezoelectric surgery device by preparing osteotomies and after mobilization of the buccal cortical by placing an autologous bone block harvested from the retromolar region as a spacer between the buccal and lingual cortical plates. Block-grafts were stabilized by osteosynthesis screws. Implant placement was carried out after a 3-month healing period.

Intervention Model

SINGLE GROUP

Model Details: * Procedure: alveolar ridge splitting * Procedure: bone core biopsy After 3 month healing time reentry took place and bone core biopsy samples were collected from the augmented bone of the maxillary sinuses with a trephine drill. Biopsy samples were collected from the sites where the dental implants were to be placed. * Device: dental implant placement During reentry after bone biopsy dental implants were placed. * Clinical measurements: Measurements were carried out using Williams probe * Histomorphometric measurements * Micro-CT analysis
