Actual (reported)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.

Actual (reported)Probing depth
lower probing depth in patients who underwent annual maintenance
10 years
Plaque control
10 years
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).
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).
The individuals will be submitted to a complete periodontal examination, with measurements obtained at four points per tooth and dental implant (mesial, distal, buccal and lingual / palatal), in all teeth / implants present, except for the third molars, the parameters evaluated will be: Probing Depth, Clinical Insertion Level, Plaque Index, Teeth Bleeding Index. The implants will be evaluated according to the parameters: presence of suppuration, probing depth, bleeding to probing and presence of biofilm around the implants. To perform the clinical examinations, the following instruments will be required: Willians millimeter probe, exploratory probe and clinical mirror. In all participants, complete periapical radiographic examinations with 14 radiographs will be performed to verify the bone cortical height level and to assist in the periodontal diagnosis.
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
Individuals of both genders, between 30 and 70 years of age, with implants placed from 2004 to 2010 will be included in the study.
