Objectives:
This study aimed to evaluate the impact of implant placement with simultaneous bone augmentation on patients' willingness to repeat the procedure. Secondary outcomes included assessing patient-reported outcome measures, clinical- and surgical-related factors affecting treatment outcomes.
Methods:
Subjects who were currently undergoing or have undergone implant placement with simultaneous bone augmentation in the esthetic region (maxillary second premolar to second premolar) were assigned to three groups: Group A (short-term), Group B (1-5 years post-surgery), and Group C (> 5 years post-surgery). Clinical assessments, dichotomous questions, and visual analogue scales were used to evaluate therapeutic outcomes according to the group of interest.
Results:
One hundred and fifty patients completed the study (n = 50 per group). In Group A, 16% experienced wound dehiscence (membrane exposure < 3 mm), and 2% had postoperative bleeding, infection, swelling, or abscess. Flaps extending beyond three teeth significantly increased early membrane exposure (p = 0.04). Patient-reported postoperative discomfort (p < 0.001) and wound healing scores (p < 0.04) decreased over time. Willingness to repeat the procedure was 100%, 88%, and 98% in Groups A, B, and C, respectively, with satisfaction rates of 98.2 ± 7.5, 91.2 ± 10.6, and 95.2 ± 10.9. No significant differences were found between Groups B and C for functional or esthetic satisfaction. However, Group C reported higher satisfaction and comfort (p < 0.001). Younger adults and women reported greater postoperative discomfort than older adults and men.
Conclusions:
Implant placement with simultaneous horizontal bone augmentation in esthetic areas shows a high willingness of patients to repeat the procedure in the short-, mid-, and long-term. Additionally, this therapeutic approach yields low rates of postoperative complications and discomfort, along with high patient satisfaction related to functional performance, esthetics, and overall comfort.
