Conditions
Summary
This randomized controlled clinical trial aims to evaluate whether reducing the healing interval for implant placement after extraction socket preservation improves clinical and radiographic outcomes compared with the conventional waiting period. Participants requiring single-tooth extraction and implant therapy will be randomly assigned to implant placement either 4 months or 6 months after ridge preservation using the Vega Plus implant system (Klockner). Clinical and radiographic assessments will be performed at baseline and during follow-up visits. The primary outcome will be the mean change in horizontal alveolar ridge width measured using cone-beam computed tomography (CBCT). Secondary outcomes will include vertical bone height changes measured on CBCT, implant stability measured using resonance frequency analysis (ISQ values), marginal bone level changes assessed on standardized periapical radiographs, and postoperative pain assessed using the Visual Analog Scale (VAS). The results of this study may contribute to optimizing treatment timing and improving efficiency in implant dentistry while maintaining favorable clinical outcomes.
Eligibility
Inclusion Criteria9
- Age: ≥ 18 years.
- Good general health.
- Need of extraction of incisors, canines or premolars due to carious lesion, endodontic complication, root fracture or prosthetic reason.
- Presence of three intact socket walls after tooth extraction with a defect of 50% or more of the buccal wall.
- Need of single-tooth implant treatment, with presence of adjacent teeth and opposing occluding teeth (for measurement stent indexing).
- Enough available bone assessed on CBCT to place implants with 3.6 mm diameter and 10 mm in length.
- Periodontal health in intact or reduced periodontium.
- Full-mouth plaque and bleeding scores < 20%.
- Able and willing to follow study procedures and instructions.
Exclusion Criteria4
- < 18 years.
- Compromised health. Existence of any systemic condition such as uncontrolled diabetes mellitus, cancer, HIV, disorders that compromise wound healing, chronic high dose steroid therapy, intravenous and oral bisphosphonate therapy, bone metabolic diseases, history of irradiation of the head and neck area, or any other immunosuppressive therapy that would contraindicate oral surgical treatment.
- Absence of any adjacent teeth or the opposing occluding teeth.
- The hopeless tooth is a molar.

Interventions
Participants receive treatment phases with a reduced time interval between sessions according to the experimental protocol in order to evaluate whether shortening the interval improves clinical outcomes and treatment efficiency.
Participants receive implant placement after extraction socket preservation following the conventional healing interval used in routine clinical practice.
