Congenitally missing teeth and/or hypodontia is a prevalent dental anomaly. There are different treatment options available for these conditions such as space maintenance, restoring the space by resin-bonded-fixed-partial-dentures (RBFPDs), and dental implants. This study addresses the comprehensive treatments for congenitally missing tooth and diastema using interdisciplinary approaches. One patient was treated with small-diameter-implants and the other one was treated using an intraoral scanner to make digital impression and fabricating RBFPDs with CAD/CAM system...

Following tooth removal, three dimensional hard- and soft-tissue loss take place. Spontaneous healing makes the defect more severe and results in collapsing tissues. Implant placement is not feasible. In the aestethic zone even fixed partial dentures will not deliver the expected result. Our aim was to demonstrate that only ridge preservation enables implant placement and also provides excellent aestetic result even at frontal areas. CBCT was made before and 6-8 months after ridge preservation. Vertical and socket area measurements were carried out and compared in pre-, and postoperative images...

AIM OF THE STUDY: It is well known by previous important studies that mandible flexes during different jaw movements. According to this assumption it is very important to know how implant supported fixed partial dentures could restrict mandibular movements and, could lead to excess strain accumulation that could modify the resolution of implant treatment. The aim of our project is to create a bio-faithful model able to recreate mandibular movements, during three point bending test methods of (FIXED -PARTIAL -DENTURES) FPDs, to avoid a not flexible metal base, where models' properties doesn't allow to obtain a bio-faithful simulation during testing phases...

Partially or totally edentulous jaws frequently undergoes from moderate to severe bone atrophy with problems of prosthetic rehabilitation. The inability to make a prosthetic rehabilitation on implants may led to the use of a partial or total removable denture with difficulties in eating and speech, ulcerations of the oral mucosa and loss of facial vertical dimension. These problems may be solved performing bone augmentation procedures. Bone grafts and distraction osteogenesis brought implant dentistry from an experimental practice to become a consolidate dental procedure...

Logical categorization of implant-supported fixed partial dentures (ISFPDs) based on implant angulation, abutment type, and screw access channel (SAC) design for screw-retained restoration is not available in the literature. This article proposes a simple classification system to describe implant angulations and prosthesis design affecting abutment selection (engaging or nonengaging) for ISFPDs. An additional classification that addresses screw access channel designs is also introduced. These classifications provide clear interpretation of clinical scenarios for ISFPD design consideration and a basis for categorization of future complications...

The Amelogenesis Imperfecta is associated with malocclusion and usually requires an interdisciplinary treatment. Due to the patient's refusal of orthodontic treatment, prosthodontics-based treatments alternative was considered and planned. The patient was treated with zirconia-based fixed partial dentures, which resulted in improved occlusion, better oral health, and improved esthetic appearance.

REVIEW
John Mamoun
Dentists often place post and core buildups on endodontically treated abutments for crown and bridge restorations. This article analyzes the bio-mechanical purposes, advantages and disadvantages of placing a core or a post and core in an endodontically treated tooth and reviews literature on post and core biomechanics. The author assesses the scientific rationale of the claim that the main purpose of a post is to retain a core, or the claim that posts weaken teeth. More likely, the main function of a post is to help prevent the abutment, on which a crown is cemented, from fracturing such that the abutment separates from the tooth root, at a fracture plane that is located approximately and theoretically at the level of the crown (or ferrule) margin...

The suitability of various post and core materials for the 4-unit zirconia fixed partial denture abutment teeth was investigated to lower stress concentration. Artificial mandibular teeth (44 and 47) were used as the abutment teeth. There were two types of posts and cores: resin composite with glass fiber posts (RC), and cast platinum gold alloy (MC). Two experimental groups were analyzed. For Group RM, the premolars were restored with RC and the molars were restored with MC. For Group MR, the premolars were restored with MC and the molars were restored with RC...
