RESEARCH Comparison Between Immediate and Delayed LaserTreated Implants Surface With Switching Platform: A Clinical Retrospective Study ´ Eduardo Jose de Moraes, MSc1* Francesco Rao Genovese, DDS2 The aim of the present study was to compare immediate (Im) versus delayed (De) placement of laser-treated implants surface with switching platform to confirm the predictability and performance of this type of implant. The implants were placed in pos exodontia and healed sites at the incisor, canine, premolar, and molar regions of the maxilla or the mandible. A protocol was prepared in which patient age, sex, implant length, diameter, and use of bone graft were recorded. The study included 44 GEASS Srl (Udine, Italy) implants with laser surface and morse taper connection, placed in 27 patients (mean age: 56 years; range: 25–80 years).The survival rates were 100% in the Im group and in the De group. The patients were followed for a minimum of 12 months. Implants with laser surface and morse connection presented when placed in fresh sockets showed similar results to implants placed in mature bone after 12 months of follow-up. Key Words: laser surface implants, morse taper connection, immediate versus delayed implants INTRODUCTION A number of scientific works have shown the predictability of osseointegrated in implant dentistry that complies with the biologic principles proposed by Adell et al and others.1–3 Among these principles was the need for complete healing of the alveolar bone before placing an implant into a fresh extraction socket, a process that usually requires 6 to 12 months. However, implants placed postextraction have proven to be a successful, predictable treatment modality.4–14 Some authors have argued that many advantages can result from placing dental implants into a fresh extraction socket. For example, it is easier to position them because of existing reference points, possible to preserve the alveolar bone and contour of the ridge, and it offers advantages for the patient including a shorter treatment time, reduction 1 ´ Oral Implantology Department, UNIFESO, Teresopolis, Brazil Private practice, Barcellona Pozzo di Gotto, Italy * Corresponding author, e-mail: edujm@uol.com.br DOI: 10.1563/AAID-JOI-D-11-00182 2 in the number of surgical appointments, and less morbidity.15,16 Placement of an implant into a fresh alveolus will usually result in a gap between the occlusal part of the implant and the bone walls. To ensure osseointegration of the entire implant, synthetic bone substitutes, membranes, bone grafting, osteoconductive substances, or a combination of these have been used to achieve bone formation in such defects. Autogenous bone and a variety of xenogenic graft materials have been employed in conjunction with immediate implantation, with many of them showing successful results. Animal studies have indicated that osseointegration of immediately placed implants in extraction sockets can be achieved without bone augmentation procedures, and with a success rate comparable to that of delayed implant placement.17–19 There are certain disadvantages that could jeopardize the success of immediate implant procedures, such as lack of soft tissue closure over the extraction site.20 Otherwise the literature presents different aspects in macro and micro morphology of implants with designs with the aim better performance.
