Developing Stability of Posterior Mandibular Implants Placed With Osteotome Expansion Technique Compared With...

Area of Science:

• Dental Implantology
• Biomaterials Science
• Surgical Techniques

Background:

• Clinical decisions on mandibular implant stability and osseointegration using bone expansion techniques are limited.
• Evaluating implant stability and osseointegration is crucial for successful dental restorations.

Purpose of the Study:

• To compare the stability of mandibular implants placed with osteotome expansion versus conventional drilling techniques over 12 weeks.
• To assess the impact of surgical technique on primary and secondary implant stability in D3 bone density.

Main Methods:

• A comparative study involving 58 implants in 33 patients with D3 bone density.
• Implants were placed using either osteotome expansion (32 implants) or conventional drilling (26 implants).
• Implant Stability Quotient (ISQ) values were measured at multiple time points up to 12 weeks post-surgery.

Main Results:

• The osteotome expansion group had lower initial bone density (64.96 ± 6.25) compared to the conventional group (68.98 ± 5.06).
• Both techniques achieved comparable primary implant stability (ISQ_b-0).
• The osteotome expansion group demonstrated a trend towards greater secondary stability increases (ISQ_b-12).

Conclusions:

• The osteotome expansion technique is viable for D3 bone ridges with mild horizontal deficiency.
• While primary stability was similar, osteotome expansion showed enhanced secondary stability over 12 weeks.
• Healing patterns and long-term osseointegration may differ between the two techniques.
