Carrot Technique Versus Guided Bone Regeneration for Horizontal Ridge Deficiency in the Maxillary Esthetic Zone

Condition(s) studied

Investigational drug(s) / intervention(s)

Carrot Technique: Implant placement with simultaneous horizontal ridge augmentation using an autogenous bone core harvested from the implant osteotomy site with a trephine drill and fixed buccally using osteosynthesis screws.

Guided Bone Regeneration: Implant placement with simultaneous horizontal ridge augmentation using bone substitute material and a collagen membrane according to guided bone regeneration principles.

Study summary

This randomized controlled clinical trial aims to compare the effectiveness of the Carrot Technique and Guided Bone Regeneration (GBR) for the management of horizontal alveolar ridge deficiency in patients requiring implant placement in the maxillary esthetic zone. Twenty patients will be randomly allocated into two equal groups. Clinical outcomes including implant stability and soft tissue healing, as well as radiographic outcomes including alveolar ridge width, bone density, and marginal bone loss, will be evaluated using clinical examinations and cone beam computed tomography (CBCT) during a 12-month follow-up period..

Eligibility

Primary outcome measure(s)

• Change in Alveolar Ridge Width — baseline and 12 Months
  Horizontal alveolar ridge width measured using cone beam computed tomography (CBCT). Changes in ridge width will be calculated by comparing measurements obtained immediately after surgery and at follow-up.
