Carrot Technique Versus Guided Bone Regeneration for Horizontal Ridge Deficiency in the Maxillary Esthetic Zone
Evaluation of the Carrot Technique With Simultaneous Implant Placement for Horizontal Alveolar Ridge Deficiency in the Maxillary Aesthetic Zone: A Randomized Controlled Clinical Trial.
調査の概要
状態
詳細な説明
The Carrot Technique is a minimally invasive approach that utilizes an autogenous bone core harvested during implant osteotomy and repositioned to augment the deficient buccal ridge. This technique may reduce donor-site morbidity while providing sufficient horizontal bone augmentation. Guided Bone Regeneration remains one of the most widely used techniques for horizontal ridge reconstruction through the use of bone substitute materials and barrier membranes.
This randomized controlled clinical trial will compare the clinical and radiographic outcomes of the Carrot Technique and GBR in patients presenting with horizontal ridge deficiency in the maxillary esthetic zone. Twenty patients requiring single-tooth implant rehabilitation will be randomly allocated into two equal groups. Group I will receive implant placement combined with the Carrot Technique, while Group II will receive implant placement combined with Guided Bone Regeneration.
Clinical evaluations will include implant stability assessed by resonance frequency analysis, soft tissue healing using the Landry Healing Index, and peri-implant inflammation using the modified sulcus bleeding index. Radiographic evaluation will be performed using cone beam computed tomography immediately after surgery and at 6 and 12 months postoperatively to assess changes in alveolar ridge width, bone density, and marginal bone loss. The study aims to determine whether the Carrot Technique provides comparable or superior outcomes to GBR for horizontal ridge augmentation associated with implant placement.

Adequate vertical bone height for implant placement. Medium to hard bone quality (D2-D3 according to Misch classification). Absence of bruxism or other parafunctional habits.
Exclusion Criteria:
- Presence of local pathological lesions (e.g., cysts or tumors) at the planned surgical site.
Poor bone quality (D4 bone). Pregnancy. Heavy smoking. Any medical condition contraindicating implant surgery.
