Immediate implants are currently considered an effective therapeutic option in maxillary and/or mandibular arch rehabilitations of edentulous or partially edentulous patients. Often the bone defi cits around the implant require regenerative therapies. Barrier membranes were often used in these
procedures and in some cases were accompanied by an early exposure in the oral cavity that could explain the poor clinical results recorded as evidence. The paper describes case of an immediate implant with a vestibular bone defi cit treated with the use of an autologous grafting of plasma rich platelet.

Interesting clinical case of a post-extraction implant in an aesthetic site with severe vestibular bone deficit, optimally rehabilitated with the use of a conical implant with switching platform emergence combined with regeneration with magnesium-enriched hydroxyapatites (Sintlife) and the “one abutment-one time” prosthetic protocol.

The implants were positioned in vivo in standard sites (Control Group), in sights with small circumferential defects (Test Group 1) and in sites with large circumferential defects (Test Group 2). No bone regeneration technique was used in the Test Groups, and the implants were left to heal in the void. At three months osteointegration was observed around all the implants, though in the Test Groups 1 and 2 the BIC was still low and a layer of dense connective tissue, directly proportional to the extent of the defect, had filled the gap. The dimensions of the defects were therefore able to influence the results. So clinically it should be borne in mind that non regenerated bone defects show longer healing times.

PROSTHETIC REHABILITATION OF AN ATROPHIC MAXILLARY AS A CONSEQUENCE OF FACIAL TRAUMA

Numeri Uno 11; 2011, 7-9

HORIZONTAL AND VERTICAL PERI-IMPLANT BONE REGENERATION WITH TITANIUM MESH AND AUTOGENOUS BONE

This article presents the technique of three-dimensional bone reconstruction in the pre-maxilla with two pieces of titanium mesh and autologous bone of intraoral origin taken with piezoelectric surgery, and simultaneous insertion in the jaw of four Kohno implants. The increases in bone volume obtained are evaluated before and after surgery, both clinically and with volumetric 3D X-ray. The possibilities of inserting osseointegrated implants also in areas with severe bone atrophy (decrease of
the available bone volumes), both vertical and/or horizontal, currently allows a solution for those situations which were previously solved with partial or total removable prostheses. The various bone regeneration techniques now have a high predictability. To be sure of obtaining a good result also in terms of predictability of a prosthetic rehabilitation on implants, especially in highly aesthetic areas, the risk factors must be assessed with great attention.
The selection of clinical cases and the planning of the case are decisive, as is also the choice of the suitable surgical and prosthetic protocol, as well as the good experience of the team of professionals who will have to deal with each clinical case.
Rightly considered among these techniques, and in the wider field of GBR, is the technique of threedimensional bone reconstruction conducted with titanium mesh, covering various bone replacement materials including mainly autologous bone, as is also highlighted in the literature. In fact the material most documented is still autologous bone, which most authors consider the “gold standard” among the various materials, as it alone possesses the biological characteristic of osteogenesis and is recognised as “self” by the organism.
Autologous bone can be taken from intraoral sites such as the mandibular symphysis, the corner of the mandible, the upright branch, the external oblique line and the tuber (all of intramembranous origin), or from extraoral sites such as the iliac crest, the external tibial plateau (of endochondral origin), or the calvaria (intramembranous origin). Titanium mesh has been used by many authors for many years, both in maxillo-facial surgery and in the oral cavity, alone or in association with implants.

CONTROLLED BONE EXPANSION WITH THE DRILL BONE EXPANDER (D.B.E.): VARIABLES AND MULTIFUNCTIONALITY

The article aims to provide a broad and as far as possible complete picture of the functions of the Drill Bone Expander (D.B.E.) System in controlled bone expansion methods. The concept of prosthetically guided implantology is now a fundamental assumption of modern implantoprosthesis, which is applied in all cases that dental surgeons have to deal with every day. This means that the position of the implant must not be dictated by where the surgeon finds an adequate quantity of residual bone tissue, but rather by scrupulous prosthetic planning, conducted a priori, which establishes the ideal point for then having a correct unloading of the forces, emergence profile, tissue management, etc.
It is also equally certain that one of the major anatomical limiting factors that can prevent the correct positioning of the implants is horizontal and/or vertical bone reabsorption. In the light of these two factors it is therefore clear that, when in the presence of bone loss such as to preclude an adequate implantoprosthetic rehabilitation, it is necessary or, even more, indispensable to resort to regenerative techniques suitable for restoring a new and sufficient bone anatomy.
For this purpose the use of the Drill Bone Expander D.B.E. System has proven, in our daily clinical practice, to be an extremely useful, simple and above all versatile method that is able to provide reliable support in many situations where we have had to resort to bone regeneration techniques. One of the most frequent situations that the surgeon has to deal with and in which the use of the D.B.E. System may be fundamental is certainly that of post-extraction implants. Very often, especially when the lack of a sufficient apical bone thickness or an inadequate density prevent the insertion of longer implants, the greatest difficulty lies in achieving a minimum primary stability that guarantees perfect osseointegration of the implant. This publication presents an interesting series of clinical cases.

20 implants were inserted in 17 patients and at the same time sinus lift was performed with a minimally invasive technique using the M.I.S.E. kit and Sintlife. At the 24-month follow-up the implants were all integrated. The mean bone height, which before the operation was on average 4.12 mm, was stable at 24 months with an important gain in all cases and a mean value of 12.98 mm.
