Retrospective multicenter analysis of immediate provisionalization using one-piece narrow-diameter (3.0-mm) implants

Area of Science:

• Dental Implantology
• Prosthodontics
• Oral Surgery

Background:

• Restoring missing teeth, particularly incisors, presents unique challenges due to aesthetic and functional demands.
• Narrow interdental spaces and limited labiolingual bone width often complicate implant-based rehabilitation.

Purpose of the Study:

• To evaluate the clinical outcomes of immediate provisionalization using one-piece narrow-diameter implants.
• To assess the predictability and survival rate of narrow implants in restoring maxillary lateral incisors and mandibular incisors.

Main Methods:

• A retrospective analysis of dental records from 36 patients who received 62 narrow-diameter (3.0-mm) one-piece implants.
• Implants were placed in a one-stage procedure with immediate provisional restorations, followed by definitive prostheses after a healing period.
• Survival rates and radiographic evaluations, including marginal bone loss, were analyzed.

Main Results:

• A 100% implant survival rate was observed over a mean follow-up of 23 months (up to 33 months).
• Mean marginal bone loss at 12 months was 0.53 ± 0.37 mm.
• Implants were successfully used for single crowns and fixed partial prostheses in incisor regions.

Conclusions:

• One-piece narrow-diameter implants are a predictable and successful option for restoring missing maxillary lateral incisors and mandibular incisors.
• This technique is particularly beneficial for cases with narrow interdental spaces and limited bone dimensions.
• Immediate provisionalization with narrow implants offers a viable treatment modality in challenging anterior implant cases.
