Artificial Intelligence/Computer Guided Ridge Splitting for Treating Horizontal Ridge Defects

Kafrelsheikh University22 enrolled

Overview

Aim of the current randomized clinical trial is to evaluate and compare the effectiveness of computer-guided ridge splitting approach assisted by artificial intelligence versus conventional approach combined with simultaneous implant Placement.

Ridge split technique is considered one of the successful horizontal bone augmentation procedures especially in maxilla for the management of horizontal ridge defects. This was adapted by Summers in 1994. Guided implant surgery was used in dental implant surgery to achieve accuracy and an overall predictability. Successful guided implant workflow depends on 3-dimensional image acquisition and precise model fabrication. Artificial intelligence application in implant dentistry has ushered in a new era of precision and efficiency demonstrating improved implant survival rates and patient satisfaction and enhance the integration of technologies with digital workflows.

Interventions

free-hand ridge splittingPROCEDURE

Midcrestal incision will be followed by reflection of full thickness flap. Midcrestal cut without vertical osteotomy will be done using piezosurgery unit, and then the cut will be extended deep to the implant length. The ridge will be expanded progressively using bone wedges. Dental implant fixtures will be placed stably with 1 mm minimal thickness of buccal bone plate. Surgical site will be completely closed, and wound edges will be sutured in a tension-free way.

AI/guided ridge splittingPROCEDURE

The patient specific guides will be placed and fixed by monocortical osteosynthesis screws at the pre-planned positions at the labial buccal mucosa. A midcrestal cut will be performed on the crest of alveolar ridge guided by the guide slits. The cuts will be expanded progressively using bone wedges through the guide slits gradually lateralize and expand the labial alveolar plate of bone, so the labial cortex will move through the intentionally created micro gap till it touches the fitting aspect of the patient specific guide. Implant drills will be inserted through the guiding holes in the surgical guide and the implant osteotomy sites will be prepared. Finally, implants will be inserted in the osteotomy sites using torque-wrench in a self-tapping fashion engaging palatal and basal bone for primary stability.

Inclusion Criteria: * The target population with inadequate bone volume for implant placement due to width insufficiency of maxillary anterior alveolar ridges. * Age ranges from 25-40 years of both sexes. * No gender restrictions were considered for initial screening. * Absence of any complicating systemic condition that may contraindicate surgical procedures and implant placement. * Adequate oral hygiene. * Eligible participants should present good general health and agree to random assignment to any of the two parallel study groups. * Participants had minimum 3 months as post extraction healing period and horizontal maxillary anterior ridge defects with at least bone width of 3 mm and bone height of 13 mm. Exclusion Criteria: * Vertical ridge defect. * Undercut on the labial/buccal side. * Thick cortical bone without cancellous bone inside. * Uncontrolled systematic disorders as, diabetes mellitus, uncontrolled periodontal disease, history of head and neck radiotherapy, smokers, pregnancy, noncompliant patients, allergy to the used medications, uncooperative individuals or those unable to attend the study follow-up appointments.

Outcomes

Primary Outcomes

alveolar ridge width

CBCT will have taken immediately after surgery, at 6 and 9 months postoperatively to evaluate ridge width using OnDemand3D™ App-3D CBCT software. The alveolar ridge width will be measured buccolingually in axial view 2 mm apical to the implant collar margin.

Time frame: 9-month.

Secondary Outcomes

vertical bone height

CBCT will have taken immediately after surgery, at 6 and 9 months postoperatively to evaluate vertical bone height. Mesiodistal vertical bone height will be measured using coronal view from a fixed anatomical landmark point to the mesial and distal marginal bone level. Moreover, sagittal view will be used to measure buccolingual vertical bone height extending from fixed anatomical reference point to the buccal and lingual alveolar crest. usinng CBCT

Time frame: 9-months
