PROSPECTIVE STUDY ON THE MAINTAINING OF THE VERTICAL BONE VOLUME IN IMPLANTS INSERTED WITH THE M.I.S.E. TECHNIQUE

20 implants, inserted in 16 patients with simultaneous sinus lift performed with a transcrestal approach using the M.I.S.E. kit and with tricalcium sulphate as filling material, presented 100% survival at the 5-year follow-up. The increase of bone dimension was stable, the vertical bone reabsorption was reduced and comparable to that obtained using elevation techniques with opening of a side window.

The results, obtained with a simple and effi cient technique for elevating the sinus with the use of a special kit containing drills and non-traumatic instruments (Minimally Invasive Sinus Elevation) are illustrated in this paper.

The authors used magnesium-enriched hydroxyapatite (MHA) to fi ll the peri-implant defects in immediate sockets and observed that the bone recovery in the presence of this fi ller helped to better preserve the profi le of the bone crest in the absence of biomaterials. The difference was not significant.

This experimental study confirms the validity of the concept of distance osteogenesis, which has already been discussed in literature. Without the use of grafting materials, the bone can regenerate itself and occupy empty spaces, increasing in the direction of the implant surface and from the bottom upwards, in times proportional to the size of the defect.

The authors histologically verified in dogs the success of implants installed in the lower jaw in connection with the procedure of vertical and horizontal crest lift with autologous bone (control) and deproteinized bovine bone mineral (DBBM test). After 3 months, all the implants were stable. Those installed in autologous bone were completely integrated with the bone, while those in DBBM presented greater integration in the section in contact with parental bone.

This work studied the dimensional changes of tissues around the implants. After insertion of post-extraction implants in dogs with the use of deproteinized bovine bone mineral (DBBM test sites) to fill the coronal bone defects around the implant without the use of grafting material (control sites), impressions were taken at baseline and at 4 months. The impressions were casted and the models at the two different periods were compared with the use of three-dimensional measuring software. The histomorphometric aspects at 4 months were also compared. The test sites filled with DBBM had a much greater capacity to maintain the vertical buccal dimension compared to the control sites.

The authors histologically tested in dogs the effective behaviour of distance osteogenesis, artificially creating peri-implant gaps of different sizes around implants inserted 3 months after dental extraction. At one month from insertion, it was noted that the peri-implant defects were being filled with newly formed bone that grew from the bottom and from the walls of the defect towards the implant surface. The gap was more or less filled in relation to its initial size, no gap was completely reconstructed.

Implant peri-apical lesion (IPL) is a periapical lesion, usually asymptomatic, in which the coronal portion of the implant achieves a normal bone to implant interface. A case of IPL following immediate implant placement and treated with guided bone regeneration (GBR) principles is described. Five-year clinical and radiographic follow-up with cone-beam assessment showed complete healing of the bone. GBR principles applied to IPL could completely solve the lesion.

IMPLANT TREATMENT FOR THIN CRESTS: SPLIT-CREST OR GBR?

Introduction: Surgical treatment on thin alveolar crests for implants has always been a difficult task, even for the most experienced implantologists. The many surgical techniques suggested in literature may confuse clinicians to a certain degree in the choice of the correct surgical technique to be used.
The main surgical techniques found in literature can essentially be divided into two basic groups:

• Split-crest techniques, which aim to divide the thin crest present into two parts to be opened out, thus creating an intraosseous bone defect delimited by the two split cortices.
• Regenerative techniques, which leave the residual thin crest intact and increase the thickness of the crest with the application of a block or particulate graft, protected by a membrane or a titanium mesh.
