Prosthesis Emergence Angle Influences Marginal Bone Level for External Connection Implants: A Cross-Sectional Study.

Purpose: To retrospectively evaluate the influence of prosthetic features on marginal bone level changes around bone-level implants with an external hex connection.

Materials And Methods: A total of 100 patients with 166 implants and cemented crowns were included. Demographic and clinical data were collected.

Single ultra-short implant rehabilitation of posterior atrophic maxillae with 5 years follow-up.

Rehabilitation of edentulous ridges, in some cases, can represent a challange for both the oral surgeon and the patient. After teeth loss, posterior sectors of the maxilla can shrink because of both the crestal resorption and sinus pneumatization. The implant placement in such cases requires invasive procedures of sinus lift and bone augmentation.

Twenty eight months marginal bone level follow-up of an immediate post-extractive implant with immediate definitive loading.

Objective: The aim of this case report was to show the marginal bone level (MBL) variation, after 28 months, around an aesthetic post-extraction implant immediate loading positioned in a 46-years-old woman.

Material And Methods: After a careful evaluation of the X-rays and CBCT images, a 4×13 conical implant was placed in seat 21 after the atraumatic extraction of the fractured element and the management of the infected area. Correct primary stability (torque 70 Ncm) was obtained by inserting the implant in a palatal position with respect to the alveolus.

Correlation Between Maxillary Canine Impaction and Facial Biotype.

Aim: The etiology of teeth impaction is still not fully understood, despite that cofactors have been considered important to develop such a clinical picture. The aim of the authors' paper was to investigate about facial biotype, about the values of inclination of the upper cuspid axis to the perpendicular to Frankfort-horizontal plane and about the distance "d" of the canine cuspid to occlusal plane: each factor was statistically compared. The authors also performed a comparative analysis on the radicular length of the left and right lateral incisors of subjects with impacted maxillary canine.

Poly D,L-Lactide-Co-Glycolic Acid Grafting Material in Sinus Lift.

The poly D,L-lactide-co-glycolic acid (PLGA) is a copolymer used in many therapeutic devices for its high rates of biodegradability and biocompatibility. The principal aim of the research was to evaluate the new bone formation, after 16 (T1) and 28 weeks (T2), in sheep maxillary sinus lift in vivo model using PLGA.Computerized tomography analysis, X-ray microanalysis, and scanning electron microscope analysis of secondary electrons (SE) and the backscattered electrons (BSE) of the samples were detected.
