Evaluation of different surface treated implants after provisionalization: A 6-month prospective study.

Area of Science:

• Dental implantology
• Biomaterials science
• Oral surgery

Background:

• Dental implants are a preferred solution for tooth replacement, necessitating predictable treatment outcomes.
• Surface modifications of implants aim to enhance osseointegration and treatment success.
• Immediate provisionalization of dental implants is increasingly popular due to patient esthetic demands.

Purpose of the Study:

• To evaluate the impact of implant surface treatment on stability during immediate non-functional loading.
• To compare the osseointegration predictability of resorbable blast media (RBM) versus alumina blasted/acid-etched (AB/AE) surfaces using implant stability quotient (ISQ).

Main Methods:

• Twenty dental implants with either RBM or AB/AE surfaces were placed.
• Implants were subjected to immediate non-functional loading.
• Implant stability quotient (ISQ) was measured at baseline, 6, and 12 weeks post-loading. Crestal bone levels, plaque index, gingival bleeding index, and probing depths were assessed over 6 months.

Main Results:

• All implants achieved desirable ISQ values by 12 weeks, indicating successful osseointegration.
• RBM surfaces demonstrated a significantly greater increase in ISQ from baseline to 12 weeks compared to AB/AE surfaces.
• No significant differences were observed in crestal bone levels or other clinical parameters between the two surface treatment groups.

Conclusions:

• Immediate non-functional loading of dental implants is a predictable treatment modality.
• Both RBM and AB/AE surface treatments support successful osseointegration and implant stability.
• RBM surface treatment may offer a more predictable osseointegration trajectory for dental implants.
