The overall impression regarding the success of dental implants (DI) in patients having undergone oral cancer therapy remains unclear. The aim of the present review study was to assess the implant survival rate after oral cancer therapy. Databases were explored from 1986 up to and including September 2010 using the following keywords in various combinations: "cancer", "chemotherapy", "dental implant", "oral", "osseointegration", "radiotherapy", "surgery" and "treatment". The eligibility criteria were: (1) original research articles; (2) clinical studies; (3) reference list of pertinent original and review studies; (4) intervention: patients having undergone radio- and chemotherapy following oral cancer surgery; and (5) articles published only in English. Twenty-one clinical studies were included. Results from 16 studies reported that DI can osseointegrate and remain functionally stable in patients having undergone radiotherapy following oral cancer surgery; whereas three studies showed irradiation to have negative effects on the survival of DI. Two studies reported that DI can osseointegrate and remain functionally stable in patients having undergone chemotherapy. It is concluded that DI can osseointegrate and remain functionally stable in patients having undergone oral cancer treatment.

    ABSTRACT: This literature review investigates the occurrence of oral squamous cell carcinoma (OSCC) around osseointegrated dental implants (DI). Databases were searched from 1989 up to and including November 2011. The eligibility criteria were as follows: (1) original studies, (2) clinical studies and case reports, (3) reference lists of the relevant original and review articles, (4) intervention: occurrence of OSSC around osseointegrated DI, and (5) articles published only in English language. Fourteen studies were included. In nine studies, the dental implant patients with diagnosed OSCC had previously been exposed to cancer. In five studies, the patients presented with a history of habitual tobacco smoking and alcohol consumption. OSCC is more likely to arise around osseointegrated DI in patients with a previous history of cancer. However, the role of other factors including tobacco and alcohol usage cannot be disregarded.

    ABSTRACT: Objectives: The aim of the present study was to review the pertinent literature with reference to the clinical efficacy of antibiotics in the treatment of peri-implantitis. Methods: To address the focused question 'Are locally and systemically delivered antibiotics useful in the treatment of peri-implantitis?' PubMed/Medline and Google-scholar databases were explored from 1992 until February 2013 using a combination of the following keywords: 'antibiotic,' 'dental implant,' 'inflammation,', 'peri-implantitis' and 'treatment'. Letters to the editor, case-reports and unpublished data were excluded. Results: Ten studies were included. In six studies, peri-implantitis was treated using a non-surgical approach (scaling and root planing), whereas in four studies, a surgical approach was adopted for treating peri-implantitis. In three studies systemic antibiotics were administered and in six studies locally delivered antibiotics were used for treatment. One study used the oral route for antibiotic delivery. In three studies, minocycline hydrochloride was locally delivered as an adjunctive therapy to non-surgical mechanical debridement of infected sites. Nine studies reported that traditional peri-implantitis treatment with adjunct antibiotic therapy reduces gingival bleeding, suppuration and peri-implant pocket depth. In one study, despite surgical debridement of infected sites and systemic antibiotic cover, nearly 40% of the implants failed to regain stability. There was no placebo or control group in eight out of the nine studies included. Conclusion: The significance of adjunctive antibiotic therapy in the treatment of peri-implantitis remains debatable.
