Surgical advantages with ITI TE^® implants placement in conjunction with split crest technique

Abstract

Implant rehabilitation of the edentulous maxilla may be somewhat problematic because of anatomic situations involving insufficient bone thickness. One approach in this situation is localized ridge augmentation with the split crest technique. This surgical approach allows the external cortical plate of the maxilla to be moved in a labial direction to gain an increase in width to introduce implants of appropriate diameter. This ongoing prospective study evaluated: (i) the surgical advantages that the new ITI TE implants have showed compared with the ITI standard solid-screw implants when placed in conjunction with the split crest technique and (ii) the implant success rate associated with 42 ITI TE implants and 40 ITI standard solid-screw implants placed in 40 patients in conjunction with the split crest technique. ITI TE implants have shown direct and indirect advantages in reducing the risk of fracture of the labial cortical plate during all the three fundamental surgical steps of this technique: (a) the ridge expansion with osteotomes; (b) implant site preparation with drills and (c) implant insertion. The overall success rates of ITI TE implants and standard screw implants were 100% and 95%, respectively. Based on the preliminary results of the present study, it can be concluded that ITI TE implants inserted in conjunction with split crest technique seem to be a promising surgical procedure to treat selected anatomic situations involving insufficient maxillary bone thickness.

The ‘Alternating Osteotome Technique’: a surgical approach for combined ridge expansion and sinus floor elevation. A multicentre prospective study with a three-year follow-up

“…As regards the ridge expansion effect of AOT, the amount of horizontal bone gain was smaller than that reported in other studies, where ERE was achieved by means of original ERE (3.5 mm), [50] the split-crest technique with ultrasonic bone surgery (2.8 mm), [22] the split-crest technique plus autogenous bone and graft biomaterial (4.8 mm), [51] the extension-crest device (3.9 mm) [52] or the two-stage split-crest technique (7.1 mm). [23,53] However, AOT reduces the risk of intraoperative complications, such as cortical plate fractures, and makes it easier to prepare an adequate implant site without the use of split-thickness flaps, sagittal osteotomy and graft biomaterials.…”

“…Ferrigno and Laureti [51] proposed a novel implant design in order to reduce the risk of fracture of the labial cortical plate during the last two steps of the split-crest technique: (1) implant site preparation and (2) implant insertion. Nevertheless, the authors observed that buccal plate fracture occurred in 5% of cases, in which removal of the cortical plate was required in order to perform a GBR technique with minced autogenous bone plus graft biomaterials.…”

“…High survival and success rates (90.7-100%) for the two systems have been individually reported in many earlier studies [24][25][26][27][28][29][30][31][32][33][34][35][36][37] . Regarding the Br In this retrospective article, most cases had been applied a delayed loading after the placement of implant.…”

Types of devices used in ridge split procedure for alveolar bone expansion: A systematic review

“…In fourteen studies, gap filling for all subjects was done, while in 4 cases selective gap filling was done. Gap filling may or may not influence the final outcome of implant success [24, 25] however, since the graft material takes part in the bone remodelling process, it expedites the healing process. Ella et al [26] advocated the use of bone filling substitutes, especially in the horizontally expanded sites as it resulted in reduced resorption around the implant bony walls.…”
