Abstract
BackgroundTo investigate the influence of soft-tissue volume grafting employing autogenous connective tissue graft (CTG) simultaneous to implant placement on peri-implant tissue health and stability.Material and methodsThis cross-sectional observational study enrolled 19 patients (n = 29 implants) having dental implants placed with simultaneous soft-tissue volume grafting using CTG (test), and 36 selected controls (n = 55 implants) matched for age and years in function, who underwent conventional implant therapy (i.e., without soft-tissue volume grafting). Clinical outcomes (i.e., plaque index (PI), bleeding on probing (BOP), probing depth (PD), and mucosal recession (MR)) and frequency of peri-implant diseases were evaluated in both groups after a mean follow-up period of 6.15 ± 4.63 years.ResultsSignificant differences between test and control groups at the patient level were noted for median BOP (0.0 vs. 25.0%; p = 0.023) and PD scores (2.33 vs. 2.83 mm; p = 0.001), respectively. The prevalence of peri-implant mucositis and peri-implantitis amounted to 42.1% and 5.3% in the test and to 52.8% and 13.9% in the control group, respectively.ConclusionSimultaneous soft-tissue grafting using CTG had a beneficial effect on the maintenance of peri-implant health.
Highlights
A major goal of implant therapy is to ensure long-term peri-implant tissue health and create appealing esthetics
Test and control groups were commonly characterized by low median plaque index (PI) scores at both patient (0.00 vs. 0.21; p = 0.093) and implant levels (0.17 vs. 0.17), respectively
The present cross-sectional analysis aimed at investigating the influence of soft-tissue volume grafting employing autogenous connective tissue graft (CTG) simultaneous to implant placement on peri-implant tissue health and stability
Summary
A major goal of implant therapy is to ensure long-term peri-implant tissue health and create appealing esthetics. To obtain these therapeutic endpoints, soft-tissue grafting procedures performed either simultaneously with or after implant placement have become an indispensable part of contemporary implant dentistry [1]. Soft-tissue grafting procedures aimed at increasing keratinized tissue have been shown to markedly improve peri-implant soft-tissue inflammatory conditions and were associated with higher marginal bone levels compared to the control sites [3]. To attenuate the undesirable changes of the soft-tissue margin, soft-tissue volume augmentation at the time of implant placement was suggested as a preventive measure [9, 10].
