Background:
The long-term success of implant-supported restorations is influenced by various implant placement techniques.
Materials And Methods:
This randomized controlled trial involved 120 patients requiring dental implants, divided into three equal groups based on the implant placement technique: Group A (conventional submerged), Group B (one-stage non-submerged), and Group C (guided surgery). All participants were followed for three years. The primary outcomes measured were implant stability (using implant stability quotient (ISQ) values) and marginal bone loss (using radiographic analysis). Secondary outcomes included patient satisfaction and prosthetic complications.
Results:
The study results demonstrated significant differences among the implant placement techniques. Group C (guided surgery) exhibited the highest mean implant stability, with an ISQ value of 75.4, outperforming Group B (one-stage non-submerged) at 73.2 and Group A (conventional submerged) at 71.5. In terms of marginal bone loss, Group A demonstrated the greatest loss at 1.5 mm, whereas Group B and Group C experienced less bone loss, measuring 1.1 mm and 0.9 mm, respectively. Patient satisfaction scores were highest in Group C, with an average of 9.2 out of 10, followed by Group B at 8.7 and Group A at 8.3. Additionally, Group A recorded the highest incidence of prosthetic complications at 15%, compared to 10% in Group B and 5% in Group C, highlighting the superior performance of guided surgery in minimizing complications and enhancing overall outcomes.
Conclusion:
Guided implant surgery demonstrated superior outcomes in terms of implant stability, reduced marginal bone loss, and higher patient satisfaction compared to conventional submerged and one-stage techniques.
