Nonresorbable sintered ceramic hydroxylapatite (HA) is widely employed for filling defects in jaw bone. The small particles used for alveolar ridge augmentation in edentulous patients or for infrabony defects due to periodontal disease tend to scatter when implanted using water or saline as the vehicle. Larger blocks of this material used for filling sockets after tooth extraction don't fit well. Studies in our laboratory where we compared bovine serum albumin, collagen and plaster of Paris as binders to prevent particle scatter during implantation suggested that plaster was most useful for this purpose. In addition to preventing scatter of the particles, plaster enables the formation of implants of any size and.shape either prior to or during surgery. Studies with the PATS reaction have indicated that plaster acts as a scaffold for the incorporation of HA particles into bone in areas where the implant contacts either host bone or periosteum. The shape and integrity of the implant is maintained by the plaster component until it is replaced over a period of days by fibrovascular tissue.

Abstract Background An accurate impression is crucial to the long-term success of dental implants. This investigation evaluated the accuracy of the open and closed implant impression techniques in partially edentulous patients who received two adjacent implants. Material and methods Forty patients received Osstem Implants (Osstem Implant System, Seoul, Korea). Two impressions were made for each patient, one using an open tray and a second with a closed tray technique. The horizontal distances between two impression copings were measured and compared to similar measurements on the master casts. Also, under a stereomicroscope (AmScop14370, Myford Road, #150, Irvine, CA 92606 USA) at a 50-fold magnification, the presence or absence of the marginal discrepancies was evaluated. Results There were no statistically significant differences regarding horizontal measurements and in the marginal relationship for the two impression techniques, except between the anterior and posterior regions, for the closed tray technique. There were also no statistically significant differences in the impression accuracy between maxillary and the mandibular arches. In addition, there were no statistically significant differences for the intraoral horizontal distances, compared to similar horizontal measurements on master casts, between the open and closed tray techniques. Conclusions Within the limitations of the present study, there were generally no differences in the impression accuracy between the open and closed tray techniques in partially edentulous patients with two adjacent implants.

Tissue Fluids

Nonresorbable sintered hydroxylapatite (HA) particles are widely used for alveolar ridge augmentation in edentulous patients to support dentures or for filling infrabony defects due to bone resorption in progressive periodontal disease. these particles tend to scatter when implanted with water or saline as the vehicle. studies in our laboratory of different binders to prevent particle scatter during implantation suggested the utility of plaster of paris for this purpose. In most operative procedures the ha/plaster mixtures moistened with water or saline set and harden adequately, especially when a small amount of potassium sulfate has been added to the plaster component to accelerate setting. when the implantation site is bloody or has an excess of tissue fluids, setting of the mixture is considerably slowed if, indeed, the plaster is not actually washed away.

Abstract Objectives To assess the long-term clinical outcomes following lateral alveolar ridge augmentation using a collagenated xenogeneic bone block (CXBB) and staged implant placement. Material and methods A total of n = 9 patients (9 implants) were available for the analysis. Each subject had received lateral ridge augmentation using a size-adapted rigidly fixed CXBB and contour augmentation at single-tooth gaps. Implant placement was performed after 24 weeks of submerged healing. Clinical parameters (e.g., bleeding on probing (BOP), probing pocket depth (PD), mucosal recession (MR)) were recorded at 16 to 20 weeks after the cementation of the crown (baseline) and scheduled for 0.5 (visit 1 (V1)), 1.5 (V2), 2.5 (V3), 3.5 (V4), and 4.5 (V5) years after implant loading. Results Changes in clinical parameters commonly remained low throughout the entire observation period. Significant changes to baseline were merely noted for mean BOP scores at V4 (19.14 ± 17.75%; n = 7; P = 0.029) and mean PD scores at V2 (0.78 ± 0.98 mm; n = 9; P = 0.044) and V3 (1.33 ± 1.05 mm; n = 9; P = 0.009), respectively. Conclusion CXBB was associated with high clinical implant success and survival rates on the long-term.
