Overview

This study aims to evaluate the clinical and radiographic outcomes of different staged ridge-splitting techniques for management of severely resorbed lower jaws in the posterior region. The study is designed as a clinical trial, so that three different interventions would be compared for a conclusion highlighting the relative best of them.

In the context of the care of severely resorbed lower jaws in the posterior region, the purpose of this study is to evaluate the clinical and radiographic outcomes of several stepwise ridge-splitting procedures. The study is supposed to be a clinical trial, with the purpose of comparing three distinct therapies in order to get a result that highlights which of them is the most effective in comparison to the others.

Interventions

Modified Ridge-SplittingPROCEDURE

Unlike the conventional ridge-splitting where bone grafting is done in the same visit after ridge splitting, modified ridge splitting involves splitting the ridge only at the first visit, then bone grafting is done either alone afterwards in the second visit (Modified 3-Staged Ridge-Splitting Group) and dental implants will be placed in the third visit, or, as in the Modified 2-Staged Ridge-Splitting Group, bone grafting and dental implants placement will be done in the second visit.

Inclusion Criteria: * Patients were free from any relevant systemic diseases according to American society of Anesthesiologists classifications. * Patients of single or multiple missing teeth in the posterior mandible. * A ridge width of minimum 4mm and a 10 mm ridge height with 2mm minimum above Inferior Alveolar Nerve (IAN) were present in CBCT images. * Absence of buccal concavities at the planned implant site. Exclusion Criteria: * History of any systemic diseases or medication that alters bone metabolism. * Poor oral hygiene. * Heavy smoker (more than 20 cigarettes/day) or alcoholic patients. * Chemotherapy or radiation therapy to the head and neck region in the last 12 months prior to the proposed implant therapy. * Patients currently on or with a history of bisphosphonate therapy.

Outcomes

Primary Outcomes

Alveolar ridge width

Radiographically via Cone-beam Computed Tomography (CBCT), the width of the alveolar bone was measured horizontally from the buccal to lingual cortex below the crest of the alveolar bone from 3 levels at 1 mm, 3 mm and 6 mm on three cross-sections by the CBCT software (OnDemand, Cybermed Inc, Korea).

Time frame: immediately after implant placement, immediately after implant loading and six months after implant loading

Secondary Outcomes

Implant stability

Smartpeg was installed in the dental implant fixture. From both buccal and lingual directions, an analyzer probe was located closer to the Smartpeg, and the implant stability quotient (ISQ) values were obtained from the Osstell Monitor

Time frame: immediately after implant placement, immediately after implant loading and six months after implant loading
