Abstract
BackgroundTo evaluate the prevalence of peri-implant disease after immediate implant placement and loading.Material and methodsThis cross-sectional analysis included a total of 47 patients with 64 implants exhibiting a mean loading time of 2 to 10 years (4.23 ± 1.7 years). The surgical and prosthetic procedures were standardized in all patients. Peri-implant health and disease was assessed based on the established case definitions.ResultsThe prevalence of peri-implant health, peri-implant mucositis, and peri-implantitis amounted to 38.3%, 57.5%, and 4.2% of the patients, respectively. Mucosal recession of 1 mm was present at 4 (6%) implants. No suppuration, pain, or implant failures were reported. Ordinal logistic regression revealed that reduced keratinized mucosa height was significantly associated with the diagnosis of peri-implant mucositis and peri-implantitis (OR = 0.514, P = 0.0125).ConclusionImmediate implant placement and loading was associated with high success rates at 2 to 10 years.
Highlights
Depending on the timing of implant installation, tooth replacement with a dental implant can be performed via four approaches: immediately after tooth extraction; early, 4‐8 weeks after the extraction; in a delayed manner, 12‐16 weeks after the extraction; or conventionally, > 16 weeks following the extraction [1, 2]
Clinical and pre-clinical studies have demonstrated that immediate implant placement at the time of tooth extraction failed to prevent physiological bone remodeling, which inevitably occurs during the establishment of the peri-implant soft-tissue complex [7, 8]
Demographic data and tooth/implant characteristics Demographic data of the study population as well as tooth/implant site characteristics are presented in Tables 1 and 2
Summary
Depending on the timing of implant installation, tooth replacement with a dental implant can be performed via four approaches: immediately after tooth extraction (type 1); early, 4‐8 weeks after the extraction (type 2); in a delayed manner, 12‐16 weeks after the extraction (type 3); or conventionally, > 16 weeks following the extraction (type 4) [1, 2]. To shorten the overall treatment time, healing period, and patient morbidity, immediate implant placement and loading have become popular treatment modalities, for single-implant cases. Clinical and pre-clinical studies have demonstrated that immediate implant placement at the time of tooth extraction failed to prevent physiological bone remodeling, which inevitably occurs during the establishment of the peri-implant soft-tissue complex [7, 8]. Findings from one pre-clinical analysis indicated two to three times higher vertical bone resorption at immediately inserted implants than at adjacent spontaneously healed sites [10]. To evaluate the prevalence of peri-implant disease after immediate implant placement and loading. Results: The prevalence of peri-implant health, peri-implant mucositis, and peri-implantitis amounted to 38.3%, 57.5%, and 4.2% of the patients, respectively.
