“…Thus, the time is considered to be important factor in the staining of the dental prostheses and these results agreed with others [14,15]. Fabrication of dental prostheses with the help of CAD/ CAM technology is related to the advantages of high-density polymers based on highly cross linked polymethylmethacrylate [16]. Those advantages include; good esthetic, low water solubility and absorption, sufficient strength, low toxicity, easy repair with simple fabrication technique [17].…”

This study starting with collection of forty study casts of children aged 2-4 years old of both gender, with prematurely lost one of the maxillary central incisors and the adjacent lateral incisor was carious and considered to be abutment tooth were involved in this study for construction of cantilever bridges (Figure 1). For each cast, two bridges were constructed; 1st one is CAD/CAM acrylic bridge and the other one is manually performed acrylic bridge (Figure 2). Construction CAD/CAM bridge: The cast was 3D scanned by special scanner (710 3D) (smart optics Sensortechnik GmbH, Germany). The design of the bridge was carried out using Exocad Program (smart optics Sensortechnik GmbH, Germany). Acrylic block (Poly-methyl methacrylate) of classic shade A1 (Ivoclar vivadent, Switzerland) was used for fabrication of the bridge using CAD/ CAM machine (Charly dental, ZI Fonlabour, France). The bridge was finished and polished very well [4]. Construction of manually acrylic bridge: Wax pattern was fabricated on cast then followed the technique of typical wax loss; the heat-cure acrylic (Ivoclar vivadent, AG, FL-9494 Schaan/Liechtenstein) of classic shade

Utilization of computer-aided design/computer-aided manufacturing (CAD/CAM) rapidly increases in dental medicine. Making of computer-engineered complete denture is based on scanning of patient data, designing of prosthesis and milling or rapid prototyping. This is digital denture, term that includes innovative devices, software programmes and corresponding materials. Industrially polymerized cross-linked polymethyl methacrylate (PMMA) is the material used for fabrication of digital denture. The aim of this study is to analyze the different cross-linked PMMA used for fabrication of CAD/CAM complete denture.

“…When dealing with bone augmentation, one of the biggest debates in the literature is the nature of the graft. Some authors recommend xenografts or alloplasts, while others opt for allografts or autografts, or even the mixing of 2 or more types [1]. Xenografts have the advantage of low to no resorption on a long term, but may have some problems when dealing with big bone defects, regarding the vascularization and bone formation [2],Allografts and autografts have the advantage of being more stable when dealing with large bone defects and also they ease the blood vessel formation [3][4][5][6].…”

Implants and biomaterials used in hard and soft oral tissue augmentation are very complex, but predictable to use nowadays, as the technological advances haven�t skipped this field of medicine. Cases that were impossible to treat with implant retained fixed prosthesis some years ago, have become the daily practice of oral surgeons and dentists around the world. The new user-friendly products, together with simplified protocols, increased the practitioners� predictability and success rate, thus the biomaterial industry took a huge leap forward. As the biomaterial industry keeps developing continuously, making better and safer products, the surgical and prosthetic protocols evolve and change as well. On this matter, the implant placement has become safer, using digital surgical guides. Guided implant placement doesn�t just allow the practitioner place the implant in the patient�s bone, but, moreover, it helps him place it in the correct, 3D, prosthetic position. And, thus, guiding the future bone augmentation and regeneration as well, accordingly. So, the implant placement has shifted from bone-orientated to prosthetic-orientated, offering at the same time a better primary stability for the implants, due to the prior planning. The present clinical study aims to analyze the outcome of the digital guided protocol. Unlike the free-handed surgery, the digital guided surgery allows dentists and oral surgeons to place implants according to the future prosthetic position of the crowns, even in conditions of alveolar ridges with bone resorption. Moreover, it makes possible the �one day implant� concept, the dental technician being able to create the provisional crown/s in advance, knowing precisely the future position of the implant placement. So, at the time of the surgery, the provisional crown is also put in place, guiding the soft and hard tissue healing and also giving the patient a greater satisfaction.
