Brief Summary:
The goal of this observational study is evaluate the association between different emergence profile angulation on marginal bone loss progression around different implant systems bone level tissue level and switching platform
Does different emergence profile angulation have the same effect on peri-implant marginal bone loss Standardized periapical radiograph that were captured after crown placement on implants will be compared with the new radiographs done after recalling the patient

Detailed Description:
The present retrospective study reported the data collected on partially edentulous patients who were restored with fixed implant supported restorations The implants were inserted in the periodontology department at the Faculty of Dental Medicine at the Saint Joseph University of Beirut Lebanon from 2012 to 2019 The study protocol received approval from the Institutional Review Board at Saint Joseph University of Beirut
Under the guidance of academic members all surgical procedures were carried out by postgraduate students For each implant system the surgical procedure followed the conventional recommendations Patients got cemented or screw-retained fixed prostheses after adequate healing time of 3 to 6 months
Patients were urged to practice proper oral hygiene after receiving their final crown Even though all patients are told to participate in a regular Supportive periodontal therapy program some of them did not they were not selected and excluded in this study Patients or implants were excluded under the following conditions a insufficient clinical records b patients with systemic diseases or conditions c smokers d irregular maintenance care e patients with calculus presence on radiographs f implants placed on reconstructed sites g implant-assisted removable prostheses h peri-implantitis diagnosis i failed implantsj Bone loss before prothesis delivery k previously treated peri-implantitis cases and lBone level implants placed supracrestally m lack of intra-oral radiographs taken using the paralleling technique at baseline the first year of prosthesis insertion and after 3 years
Patients were called for reassessment appointments after 3-7 years After signing the informed consent measurements by a PCP-15periondontal probe probe of plaque index FMPS and bleeding on probing FMBS are indicated on the form If the smoking status has changed it is also mentioned
For data analysis the following categories were included implant connection type bone-level platform switching bone-level non platform switching or tissue level Emergence Angle mesial and distal separately Emergence Profile mesial and distal separately location history of periodontitis abutment height Radiographic and clinical parameters taken at the time implant placement after prosthetic delivery and following a minimum of 3 years follow-up visit were provided
Single and multiple restorations were included
