Maxillary Atrophy

The aim of this study was to evaluate the survival and clinical success rate, complications, and patients’ quality of life after computer-aided rehabilitation supported by zygomatic implants in cases of severe maxillary atrophy (ten patients) and in bone defects in oncologic patients (ten patients). All patients underwent computer-aided planning and surgery. Seventy-three zygomatic implants were placed. The mean follow-up period was 39.9 months. Implant survival and clinical success rate, the effectiveness of planning the implant length, biological and prosthetic complications, and the quality of life were evaluated. The five-year implant survival rate for patients with maxillary atrophy and oncologic patients was 97.4% and 96.7%, respectively. The prosthetic survival rate was 100%. Two implant failures occurred in the first year. One implant failure was observed in each group. Minor biological and prosthetic complications occurred in both groups without significant differences. All complications were managed without affecting the treatment. The quality of life increased by 71.3% in the atrophic group and by 82.9% in the oncologic group. Zygomatic implant rehabilitation seems to be a reliable technique for patients with maxillary atrophy and for oncologic patients. The three-dimensional computer-aided approach allows the surgeon to plan the surgery and increase its predictability. Early prosthesis loading certainly allows for better functional outcomes.

Implant Restoration

This retrospective analysis was undertaken to evaluate the effect of immediate implant restoration using a computer-assisted technique in partially edentulous sites on interimplant and intertooth bone level stability and papilla formation. Nine partially edentulous patients received a total of 23 implants that supported immediately placed implant restorations. Planning was accomplished using a radiographic guide, which allowed visualization of the emergence profile from the platform of the implant to the cervical of the planned restoration. Guided implants were placed according to the manufacturer's instructions, and restorations were screw retained directly to the implant. Multiple implants were splinted at surgery with autopolymerizing resin. Measurements were made at a mean of 545 days (range 288–958) postoperatively on the basis of radiographs and photographs. Measures were: (1) distance from bone crest to platform, (2) bone crest to contact point, (3) interimplant distance at the outer diameter of the platform, and (4) papilla from highest point to a reference line. At follow-up time, the bone ridge was located higher than the implant platform (mean 0.57 mm) compared to implants whose interimplant distance was less than 3 mm (mean 0.27 mm). Mean increase of the bone level between insertion and approximate 1-year follow-up was 0.047 mm. The mean distance from the contact point to bone was 2.39/3.93 mm postoperatively, resulting in 91/71% papilla fill between implants and between implant and adjacent tooth, respectively. Computer-assisted surgery with the preplanned immediate restoration seems to be an effective method to minimize bone loss at the implant platform resulting in support for papilla.
