Inappropriate Protocol of Implant Placement in Contact with Impacted Teeth Leading to Failure.

Tooth impaction is a frequent phenomenon in patients with craniofacial syndrome, and the oral rehabilitation of such cases is considered a therapeutic challenge for the clinician. Placing implants in contact with impacted teeth may provide an alternative treatment for patients who refuse invasive surgery, and for whom orthodontic traction and surgery are not possible. However, the absence of evidence-based guideline protocols may sometimes lead to inappropriate execution by the clinician.

Correlation between facial measurements and vertical dimension of occlusion among Tunisian populations: An anthropometric study.

Establishing an accurate occlusal vertical dimension (OVD) is a crucial clinical step during full-mouth rehabilitation. Various techniques have been suggested to evaluate OVD, but none of them is practically reliable, and each one has its shortcomings. The correlation between facial proportions and the lower third of the face is a reliable method but needs to be verified in many ethnic groups.

Disc displacement without reduction: a retrospective study of a clinical diagnostic sign.

Objective: The purpose of this retrospective study is to evaluate a clinical diagnostic sign for disc displacement without reduction (DDWR), the absence of additional condylar translation during opening compared with protrusion.

Method: Thirty-eight electronic axiographic and magnetic resonance imaging (MRI) examinations of the TMJ were analyzed in order to compare the opening/protrusion ratio of condylar translation between non-painful DDWR and non-DDWR.

Result: According to the Mann-Whitney U test, the opening/protrusion ratio in non-painful DDWR differs significantly from non-DDWR (p < 0.
