Effect of Laser Microtextured Collar Implants on Soft Tissue Integration and Crestal Bone Level

Area of Science:

• Dental Implantology
• Biomaterials Science
• Periodontology

Background:

• Long-term dental implant success depends on peri-implant soft tissue attachment and crestal bone maintenance.
• Laser microtextured collars aim to improve tissue adhesion and reduce bone loss.

Purpose of the Study:

• To compare the clinical and radiographic outcomes of laser microtextured collar implants versus machined collar implants.
• To evaluate the effect of collar surface on peri-implant soft tissue and bone levels.

Main Methods:

• A randomized controlled trial involving 40 patients with posterior mandibular implants.
• Two groups were compared: laser microtextured collar implants (Group A) and machined collar implants (Group B).
• Clinical parameters (probing depth, bleeding on probing, mucosal thickness) and crestal bone levels were assessed over 12 months.

Main Results:

• Group A exhibited significantly lower probing depth (2.1 mm vs. 2.8 mm) and bleeding on probing (10% vs. 35%) at 12 months.
• Crestal bone loss was significantly reduced in Group A (0.39 mm) compared to Group B (0.74 mm).

Conclusions:

• Laser microtextured collar implants demonstrate superior soft tissue integration and reduced crestal bone loss.
• These implants show potential for enhancing peri-implant tissue stability and improving long-term implant survival rates.
