History of Chronic Periodontitis Is a High Risk Indicator for Peri-Implant Disease
Brazilian Dental Journal, 2013
The success rates in implant dentistry vary significantly among patients presenting previous history of periodontitis. The aim of this study was to evaluate if patients with history of chronic periodontitis (CP) are more susceptible to peri-implant disease (PID) than those without history of CP. Two hundred and fifteen individuals, under periodontal maintenance, presenting 754 osseointegrated implants, were selected for this study. The patients were divided into two groups according to the peri-implant status: Control group (patients without PID; n=129) and PID group (patients with PID; n=86). All peri-implant regions were clinically evaluated, including analyses of mucosa inflammation, edema and implant mobility. Periapical radiography assessed the presence of peri-implant bone loss. According to the clinical/radiographic characteristics, patients in Control and PID groups were diagnosed as having CP or not. Nominal variables were evaluated by the chi-square test. The distribution ...

The aim of this study is to evaluate the factors of implant failure in patients with periodontitis and their impact on the prognosis of having a peri-implant disease and/or implant failure. Data regarding 325 implants among 84 patients with periodontitis were retrospectively examined. Patients were classified by Stage (I, II, III, IV) and Grade (A, B, C), implant failures for peri-implant disease and lack of osseointegration. Clinical data, including implant- and patient-related variables were evaluated by principal components analysis (PCA) and two-step cluster analysis (CA). Survival and success rates were 96.3% and 87.1%, respectively. Prevalence of peri-implant disease was significantly higher in Stage IV patients (p < 0.05), and incidence of lost implant due to peri-implantitis was significantly higher in patients with bone augmentation (BA) (p < 0.05). PCA and CA revealed five of eleven variables and four clusters at patient level, and six of fourteen variables and three...
Is History of Periodontitis a Risk Factor for Peri-implant Disease? A Pilot Study
International Journal of Oral & Maxillofacial Implants, 2018
The aim of this pilot study was to evaluate clinical outcomes of implant treatment in periodontally compromised patients. Materials and Methods: Partially edentulous patients who were diagnosed and treated for chronic periodontitis and later rehabilitated with implant-supported single crowns or fixed partial dentures were enrolled in this study. At the final follow-up, data on probing pocket depth and bleeding on probing were collected, and changes in peri-implant bone levels were assessed on periapical radiographs. Accordingly, patients were categorized into peri-implant disease-free (PID-free), peri-implant mucositis (PIM), or peri-implantitis (PI) groups. Additionally, information on the history of systemic diseases was obtained and correlated with the findings. Results: Seven females and six males with a mean age of 55.2 (standard deviation [SD] ± 8.38) years were included in this study. Fifty-five implants were placed in 13 partially edentulous patients with a history of chronic periodontitis. The mean follow-up in the study was 35.1 (SD ± 2.40) months. No implants were lost in the 13 patients, for a cumulative survival of 100%. PI was confirmed in 3 patients and PIM in 8 patients, while 2 patients were found to be PID-free. Diabetes and hypertension were found to be the predominant systemic factors among patients affected by peri-implant diseases. Conclusion: Patients with a history of periodontitis are at considerable risk of being affected by peri-implant mucositis, if not by peri-implantitis.

Objectives: To explore peri-implant health (and relation with periodontal status) 4-5 years after implant insertion. Study Design: A practice-based dental research network multicentre study was performed in 11 Spanish centres. The first patient/month with implant insertion in 2004 was considered. Per patient four teeth (one per quadrant) showing the highest bone loss in the 2004 panoramic X-ray were selected for periodontal status assessment. Bone losses in implants were calculated as the differences between 2004 and 2009 bone levels in radiographs. Results: A total of 117 patients were included. Of the 408 teeth considered, 73 (17.9%) were lost in 2009 (losing risk: >50% for bone losses ≥7mm). A total of 295 implants were reviewed. Eight of 117 (6.8%) patients had lost implants (13 of 295 implants installed; 4.4%). Implant loss rate (quadrant status) was 1.4% (edentulous), 3.6% (preserved teeth), and 11.1% (lost teeth) (p=0.037). The percentage of implant loss significantly (p<0.001) increased when the medial/distal bone loss was ≥3 mm. The highest (p≤0.001) pocket depths were found in teeth with ≥5mm and implants with ≥3mm bone losses, with similar mean values (≥4mm), associated with higher rates of plaque index and bleeding by probing. Conclusions: The significant bi-directional relation between plaque and bone loss, and between each of these two parameters/signs and pocket depths or bleeding (both in teeth and implants, and between them) together with the higher percentage of implants lost when the bone loss of the associated teeth was ≥3 mm suggest that the patient's periodontal status is a critical issue in predicting implant health/lesion.
Journal of periodontology, 2018
A classification for peri-implant diseases and conditions was presented. Focused questions on the characteristics of peri-implant health, peri-implant mucositis, peri-implantitis, and soft- and hard-tissue deficiencies were addressed. Peri-implant health is characterized by the absence of erythema, bleeding on probing, swelling, and suppuration. It is not possible to define a range of probing depths compatible with health; Peri-implant health can exist around implants with reduced bone support. The main clinical characteristic of peri-implant mucositis is bleeding on gentle probing. Erythema, swelling, and/or suppuration may also be present. An increase in probing depth is often observed in the presence of peri-implant mucositis due to swelling or decrease in probing resistance. There is strong evidence from animal and human experimental studies that plaque is the etiological factor for peri-implant mucositis. Peri-implantitis is a plaque-associated pathological condition occurring ...
Interrelationship between Periodontitis and Peri-Implantitis: Myth or Reality?
International journal of scientific research, 2015
Introduction: With the evolution of treatment strategies over the years, we have come a long way from the era of removable partial dentures for edentulous ridges to implant supported superstructures in the current times. Implants have shifted from a complex and expensive option to a first line and feasible choice. So it has become the need of the hour to weigh the potential risk factors for the placement of implants. Peri-implantitis is one such factor causing the late failure of implants .Thus it is elaborated here to aid in proper treatment planning. Clinical Significance: Periodontitis is one of the leading causes of tooth loss all over the globe. It is said to have a multifactorial etiology making it often difficult to understand and treat. After loss of teeth either partially or completely, the question arises that will the implants which replace the missing teeth also face the same fate and have peri-implantitis causing implant loss. Thus it is clinically relevant to examine t...
Prevalence of Peri-Implantitis: A Multi-Centered Cross-Sectional Study on 248 Patients
Dentistry Journal, 2020
The aim of this multicenter cross-sectional study was to determine the prevalence of peri-implantitis and to assess its association with several patient- and implant-related factors. Patients with at least one implant, who came for a recall visit to one of the four centers over a period of five months, were enrolled. Presence of peri-implantitis (defined as bleeding on probing, exudate/suppuration, bone loss > 0.2 mm/year and increased pocket depth) and several other variables (e.g., smoking habits, history of periodontitis, diabetes) were recorded. Out of 248 enrolled patients (1162 implants), 10 patients had at least one implant with peri-implantitis (4.03%); a total of 14 implants were affected (1.20%). A statistically significant association between peri-implantitis and diabetes was found (OR 8.65; CI: 1.94–38.57). Smoking more than 10 cigarettes per day (OR: 0.53; CI 0.03–9.45) and history of periodontitis (OR: 2.42; CI: 0.49–11.89) were not found to be statistically associa...
Correlation of periodontal status of the adjacent teeth to implants and peri-implantitis
2020
There is a strong similarity between chronic periodontitis and peri-implantitis. Both periodontitis and peri-implantitis are caused by a bacterial infection by microorganisms located in the dental biofilms. Also these two conditions show similar clinical features such as soft tissue inflammation and alveolar bone defects on the teeth or dental implants. Peri-implantitis is defined as infection around the body or the apex of the implant followed by alveolar bone loss around the implant. This inflammatory process if not treated could lead to the complete loss of the implant-supported prosthodontic restoration. These clinical features are similar for the chronic periodontitis. Clinically, the inflammatory process in peri-implantitis and in chronic periodontitis can be presented as bleeding on probing, deepened periodontal pockets and periodontal suppuration. But there is one importance difference- the inflammation of the peri-implant tissues develops faster than that of the periodontal...

Background: Previous history of periodontitis associated with smoking and poor oral hygiene are considered as one the risk factor for periimplantitis which in-turn leads to implant failure. Periodontitis is regarded as the most prevalent infectious diseases with around 75% of adults being affected. A similarity between the pathogenesis of periodontitis and periimplantitis is as a result of intra-oral translocation of periodontal pathogen from teeth showing periodontitis to the peri-implant niche. Aim: The main aim of the study is to evaluate the prevalence of peri-implantitis in patients suffering from periodontitis. Material and Methodology: A retrospective study was conducted in the department of periodontology on 30 patients suffering from periodontitis and with dental implant insertions. In all the patients, periodontal and bone conditions were evaluated. Probing depth, gingival recession, clinical attachment levels, and radiographic bone loss was calculated around the implants, adjacent teeth and contralateral teeth to evaluate correlation between periodontitis and implant failures. Results: On evaluation of results with 30 patients, periodontal depth, clinical attachment levels, and gingival recession showed statistically significant around implants when compared with the periodontal parameters around the adjacent teeth and contra-lateral teeth. Non significant results were obtained when radiographic bone loss was evaluated. Conclusion: Within the limitations of the study, it was concluded that dental implant therapy is strongly affected by the periodontal health and health of adjacent teeth plays an important role in determining the failure or success of the implant while contra-lateral teeth have no or minimal relationship between periodontitis and implant failure.
Peri-implant diseases: Consensus Report of the Sixth European Workshop on Periodontology
Journal of Clinical Periodontology, 2008
Issues related to peri-implant disease were discussed. It was observed that the most common lesions that occur, i.e. peri-implant mucositis and peri-implantitis are caused by bacteria. While the lesion of peri-implant mucositis resides in the soft tissues, periimplantitis also affects the supporting bone. Peri-implant mucositis occurs in about 80% of subjects (50% of sites) restored with implants, and peri-implantitis in between 28% and 56% of subjects (12-40% of sites). A number of risk indicators were identified including (i) poor oral hygiene, (ii) a history of periodontitis, (iii) diabetes and (iv) smoking. It was concluded that the treatment of peri-implant disease must include anti-infective measures. With respect to peri-implant mucositis, it appeared that non-surgical mechanical therapy caused the reduction in inflammation (bleeding on probing) but also that the adjunctive use of antimicrobial mouthrinses had a positive effect. It was agreed that the outcome of non-surgical treatment of peri-implantitis was unpredictable. The primary objective of surgical treatment in peri-implantitis is to get access to the implant surface for debridement and decontamination in order to achieve resolution of the inflammatory lesion. There was limited evidence that such treatment with the adjunctive use of systemic antibiotics could resolve a number of periimplantitis lesions. There was no evidence that so-called regenerative procedures had additional beneficial effects on treatment outcome.
