PERI-IMPLANT BONE REGENERATION WITH BIPHASIC TRICALCIUM PHOSPHATE AND POLYLACTIC ACID

A clinical trial was carried out on 27 patients. When their implants were inserted, a bone filler material was used, composed of hydroxyapatite (HA), beta tricalcium phosphate, (TCP) and polylactic acid (PLA) combined in the same product. TCP is an osteoinductive material that is completely and physiologically resorbed. The HA acts as an indispensible support for the facilitation of bone regeneration. PLA has a double function, on the one hand the stabilization of the TCP and HA, and on the other as an occlusive barrier in bone regeneration procedures.
This has been used as a graft in cases of preservation of the crest, dehiscences and in association with the insertion of immediate implants. The radiological results (density similar to bone), clinical results (functional implant) and results for soft tissues (keratinized gingiva without inflammation) were highlighted in all cases, and the most frequent complication was the exposure of the graft material, which occurred as a consequence of secondary epithelialization granulation tissue.
Simplicity of management, the easy treatment of complications and the effectiveness demonstrated during the study make it possible to use the combination of TCP, HA and PLA in bone regeneration procedures in the field of implantology.

The osteointegration of implants positioned in sites previously regenerated with native bone and with deproteinized bovine bone mineral particulate was tested in vivo. Three months after the operation, all the implants were well integrated, in the sites where there had been serious original defects some residual particles of deproteinized bovine bone mineral could still be found.

MAXILLARY SINUS AUGMENTATION OBTAINEO BY USING PLATELET-RICH PLASMA IN COMBINATION WITH CALCIUM SULFATE. CASE REPORTS

The sinus lift procedure with the use of Platelet Rich Plasma (PRP) and the simultaneous insertion of the implants, rehabilitated in the second surgical step at 6 months, provide excellent clinical results.

This study analyses a series of sinus lifts in presence of very severe maxillary atrophy that presented complications during healing. The cases were subsequently completed with the insertion of implants. The most frequent complications occured in smokers.

COMPARATIVE CLINICAL EVALUTATION ON THE USE OF A POLYLACTIC AND POLYGLYCOLIC ACID COPOLYMER IN THE SINUS LIFT

This study compared the rehabilitation protocols with an autologous/heterologous bone mix and PLGA in the sinus lift, with simultaneous implant insertion. Both procedures demonstrated good effi cacy and reliability.

The behaviour of the ZirTi surface is histologically evaluated in a series of sinus lift procedures with nanocrystalline hydroxyapatite grafting and simultaneous insertion of experimental micro-screws in titanium. After 3 months, the histologic control demonstrated well-mineralised bone and no connective tissue interposition.

This clinical study evaluated the surgical procedure, implant stability and crestal bone reabsorption in 30 sinus lift cases with simultaneous insertion of the Global fixture. The implants were loaded after 2 weeks using the platform switching concept. Excellent results were obtained thanks to careful selection of patients, use of suitable implants and grafting materials, meticulous surgical procedure, periodontal monitoring and correct prosthetic follow-up.

A radiographic survey was conducted on the behaviour of bone around 282 implants inserted in lifted sinuses with different variables: autologous bone from the iliac crest compared to bovine bone, implants placed at the same time as the sinus lift procedure compared to deferred implant placement. At 24 months, the implant survival rate was higher in the group rehabilitated with implants placed at the same time as the sinus lift procedure (99.3%) compared to deferred implant placement (96.5%); crestal bone reabsorption was signifi cantly lower in the group treated with bovine bone compared to the one treated with autologous bone. Within the fi rst group, the crestal bone reabsorption at 2 years was in turn signifi cantly less in cases where the implants were placed at the same time as the sinus lift procedure compared to deferred implants.
