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.

Reverse Total Shoulder

Placement of the glenoid component in reverse total shoulder arthroplasty (rTSA) is of paramount importance and can affect a patient’s range of motion postoperatively. Preoperative planning and computer assisted surgery (CAS) can improve upon glenoid placement, but such systems for rTSA have experienced limited commercial success. Postoperative surgical reports from the first 1702 clinical cases of a commercially available CAS rTSA system were collected and analyzed for implant selection, implant placement, and incision start to incision close operative time, and compared to similar date cohorts for non-navigated cases. Navigated rTSA cases had a significantly longer incision time than non-navigated cases. Augmented glenoid components were used in a much higher percentage of navigated cases than non-navigated cases, suggesting that augmented glenoid components provide utility for correcting pathologic glenoid wear. The average resultant version and inclination of the implanted component increased with the size of augment used, suggesting there may not be a clear consensus on optimal version or inclination. Long term clinical follow up will need to be collected to determine if preoperative planning combined with more precise and accurate glenoid component positioning leads to improved clinical outcomes and implant longevity.

Introduction: Total knee replacement (TKR) is considered one of most successful treatment in treating knee arthritis. It aims at restoring neutral mechanical axis, balanced ligaments and normal Q angle. Surgeons have been using manual jig to achieved perfect implant placement. Since 2002 computer assisted surgery (CAS) is gaining popularity in TKR surgery to improved accuracy of implant placement. In a large meta-analysis by Bauwen’s et al, computer assisted surgery reduced number of patients with post-operative malalignment >3 degree. In another study by Kim et al found there was no no difference in alignment between computer assisted and conventional method TKR in bilateral TKR with one using conventional and the other computer assisted. In our study we compared the functional outcome between these two methods. Materials and Methods: This was a cross-sectional study conducted in Penang General Hospital comparing the functional outcome using SF-36 questionnaire and Hospital for Special Surgery (HSS) knee scoring. It involved 35 knees in each arm. All patients were operated by single surgeon using same type of implant and navigation system. Patients with post-operative complications were excluded. Results: We found that there was no significant difference (p<0.05) in both SF-36 and HSS knee score using U Mann Whitney test. Conclusion: There was no difference in functional outcome between conventional TKR and CAS.
