Does the manual insertion torque of smartpegs affect the outcome of implant stability quotients (ISQ) during resonance frequency analysis (RFA)?

Background: There is disagreement about the optimal torque for tightening smartpegs for resonance frequency analysis (RFA). Subjective finger pressure during hand tightening could affect the reliability of the resulting values. The aim of the current study was therefore to assess whether or not the insertion torque of a smartpeg magnetic device influences the implant stability quotient (ISQ) value during RFA.

[Gingival recessions and periodontal plastic surgery].

Periodontal plastic surgery is defined as the set of surgical procedures that are performed to prevent or correct developmental disorders and anatomical, traumatic and pathological abnormalities of the gingiva, alveolar mucosa, and alveolar bone. Root coverage procedures fall under this term and have been applied for more than fifty years with varying degrees of success. There are several indications for the treatment of gingival recessions.

[Gingival recessions and orthodontics].

Gingival recessions represent the most visible periodontal disease. The prevalence of gingival recessions is high. The root surface is literally exposed to negative influences such as erosion, abrasion, discoloration and decay.

Root proximity as a risk marker for periodontal disease: a case-control study.

Aim: The aim of this study is first, to examine the prevalence, symmetry and spread of root proximity using the measurement tools and classification as described in part I of the study, and second to examine whether root proximity is a risk marker for periodontal disease.

Material And Methods: The radiographs of 227 patients were examined. The study consisted of a study group of 197 patients with advanced periodontal disease with at least one site with bone loss more than one third of the root length and 30 controls without periodontal disease.

Classification, reproducibility and prevalence of root proximity in periodontal patients.

Aim: The primary aim of this study is to define and classify root proximity. The secondary aim is to examine the reproducibility of the measurement tools, to study the prevalence per inter-dental area and to examine whether the distance from the cemento-enamel junction (CEJ) to the bone crest (BC) differs between sites with root proximity and their contra-lateral sites without root proximity.

Material And Methods: In order to indicate the location of root proximity, a modification of the Shei ruler was developed, dividing the roots into three equal parts.
