Comparison of stability changes of various palatal implants

Area of Science:

• Biomaterials Science
• Dental Implantology
• Orthodontics

Background:

• Palatal implants are crucial for orthodontic anchorage.
• Assessing implant stability is vital for successful osseointegration.
• Surface modifications can influence implant-osseointegration dynamics.

Purpose of the Study:

• To compare the early-stage stability of chemically modified sandblasted/acid-etched (modSLA) titanium palatal implants against standard sandblasted/acid-etched (SLA) implants.
• To evaluate the impact of surface treatment on bone healing and implant stability.

Main Methods:

• 40 adult subjects were randomly assigned to modSLA (test) or SLA (control) groups (n=20 each).
• Implant stability was measured weekly using resonance frequency analysis (RFA) for 12 weeks.
• Implant Stability Quotient (ISQ) values were recorded to quantify stability.

Main Results:

• Initial ISQ values were comparable between modSLA and SLA groups.
• Both groups showed initial stability fluctuations, with a general decreasing trend after 2 weeks.
• modSLA implants demonstrated an increasing ISQ trend from 4 weeks, reaching baseline levels by 6 weeks.
• SLA implants showed a trend change at 5 weeks, returning to baseline by 9 weeks.
• After 12 weeks, modSLA implants exhibited significantly higher ISQ values (78.68 ± 2.9) than SLA implants (75.5 ± 3.19).

Conclusions:

• Chemical modification of the SLA surface positively influences osseointegration.
• The modSLA surface promotes faster healing and enhanced implant stability.
• This surface modification holds significant potential for improving palatal implant outcomes.
