BACKGROUND: Mandibular reconstruction after ablative surgery is challenging not only for the amount of bone tissue needed following bone loss after benign or malignant tumor surgical removal, but mainly to reconstruct bone shape and structure necessary for subsequent implant insertion to preserve the function (speech, swallowing and chewing) and aesthetic of the lower face. Several different techniques for maxillary bone defects reconstruction have been described. The aim of our work is to describe a new technique for mandibular reconstruction that uses an intramural distractor, which is placed in one surgical step and without the need for a skin incision...

Insufficient crown height space, particularly in the interforaminal region of edentulous ridges with knife-edge morphology, may prevent successful prosthetic rehabilitation. Such conditions require osteoplasty, which might complicate computer-guided implant placement. This clinical report illustrates the treatment of a patient with complete edentulism rehabilitated with a mandibular implant-supported fixed dental prosthesis by using a virtually guided approach. Both alveolar ridge reduction and prosthetically driven implant insertions were computer-guided by surgical stents to increase accuracy and predictability...

Recent years have seen increasing demand for treatments aimed at improving dental esthetics. In this context, both patients and dentists prefer to preserve dental structures as far as possible; thanks to technological advances, especially in adhesive dentistry, new materials and minimally invasive techniques such as "no-prep" (no preparation) veneers have made this possible. Nevertheless, no-prep veneers have specific indications and suffer certain disadvantages. OBJECTIVES: This clinical case describes the rehabilitation of the upper anterior region by means of no-prep veneers, with BOPT (Biologically Oriented Preparation Technique) cervical margins...

BACKGROUND: The success of prosthetic rehabilitation in patients with removable dentures depends on the achievement of the aesthetics, phonetics and most of all, proper use in the mastication process. All the patients that receive removable prostheses need a feeding education program. They must cut the food into smaller pieces, extend the length of time necessary for chewing and place the food upon both the right and left sides of the mouth at once. Bilaterally chewing with dentures will contribute to increased efficiency and denture stability during mastication...

The success of implant-based treatment is dependent on the correct restorative position of dental implants in the oral cavity. Often, the final prostheses require dental implants to be placed at sites with inadequate native hard and soft tissue. Bone augmentation procedures and materials have been extensively studied in the literature and various techniques have been developed over time to obtain adequate hard tissue at proposed implant sites. In the recent past, few publications have also studied soft tissue development at planned implant sites...
