Details and patient eligibility

About

The convenience sample to be included in the present study will consist of all individuals who had implants installed at the Dentistry Clinic of the University Santo Amaro, between the years 2004 and 2010. The following criteria will be evaluated: age; sex; presence of systemic disease; area in which the implant was installed; implant diameter and height; type of prosthesis installed; presence of bone resorption and annual maintenance.

Full description

The control of biofilm around implants is fundamental to the success of implant therapy, and it is the duty of the dentist to inform, guide and maintain patients in order to avoid pathological processes that may lead to the loss of the implanted component. The objective of the present study will be to evaluate by clinical and radiographic parameters the condition of oral implants placed for more than five years. The convenience sample to be included in this study will be composed of all individuals who had implants installed at the Dental Clinic of the University Santo Amaro, between 2004 and 2010. The following criteria will be evaluated: age; sex; presence of systemic disease; area in which the implant was installed; implant diameter and height; type of prosthesis installed; presence of bone resorption and annual maintenance. The success and survival rate of implants through the following parameters: pain; mobility; card index (IP); bleeding rate (IS); probing depth (PS); probing bleeding (SS) that will be measured on four faces by implant: mesial, buccal, distal and lingual / palatine. For the evaluation of bone loss, a conventional periapical radiograph will be performed at the moment of patient recall. Radiographs will be scanned and analyzed using Image Tool software to verify and determine the resulting linear distance between the implant shoulder and the bone crest. Factors such as smoking, annual maintenance appointments will be related to the presence of peri-implantitis.

Enrollment: 182 patients

Sex: All

Ages: 30 to 70 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• After evaluation, individuals may be allocated into groups according to the characteristics observed, for example: carriers of single implants, patients with overdentures, individuals with systemic diseases, smokers.

Exclusion criteria

• Individuals who need to use or suspend systemic medication to perform the proposed clinical exams will be excluded from the study.

Trial design

182 participants in 2 patient groups

Health

Description:

For each patient we evaluated the Probing Depth (PD), measured in mm, and the following dichotomous variables: plaque index (absent or present), gingival index (absent or present), occurrence of annual maintenance (absent or present), tooth position (anterior or posterior) and the patient's smoking habit (absent or present).

Treatment:

Other: Periodontal clinical exam
