Reduced Time Interval for Implant Placement After Extraction Socket Preservation Using the Vega Plus Implants

The optimal interval between treatment phases remains uncertain in several clinical settings. Traditional protocols often include a waiting period between phases to allow tissue healing or stabilization; however, prolonged intervals may extend overall treatment time and potentially affect patient adherence and outcomes. Emerging evidence suggests that reducing the interval between phases could maintain clinical effectiveness while improving efficiency and patient satisfaction. This randomized controlled trial will compare a reduced-interval protocol with a conventional-interval protocol. Eligible participants who require multi-phase treatment will be randomized into two groups: (1) reduced-interval treatment and (2) standard-interval treatment. Clinical examinations will be conducted at baseline and at scheduled follow-up visits according to the study protocol.

Primary outcomes will assess clinically relevant parameters associated with the treated condition. Secondary outcomes will evaluate treatment duration, patient-reported symptoms, and quality-of-life measures. Statistical analyses will compare outcomes between groups to determine whether the reduced-interval approach provides equivalent or improved results compared with the conventional schedule.

Inclusion criteria

• 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 criteria

• < 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.
