STATEMENT OF PROBLEM: Proper proximal contact is important for maintaining and stabilizing the dental arch. However, the proximal contact strength (PCS) is not a constant value and can be affected by a variety of factors. PURPOSE: This study examined the influences of postural changes on the posterior PCS. MATERIAL AND METHODS: Twelve adults with a normal occlusion and had not undergone prosthetic treatment or proximal restoration were participated in this study. A metal strip was inserted into the proximal surface and removed at a constant velocity. The contact strength was measured in every contact point between canine to second molar in both arches. The PCSs were obtained initially in the upright position, secondly in the supine position and finally in the upright position again. All measurements were repeated after a 2 hour period. Statistical analysis was carried out using the Friedman test (P < .05). RESULTS: Generally, a decrease in PCS occurred when the posture was changed from the initial upright to supine position, while it increased when the posture was changed from the supine to upright position. A significant change was observed in all areas except for between the canine-first premolar in the maxilla and between the first molarsecond molar in the mandible areas. CONCLUSION: The posterior PCS, which dentists generally believe to be a static feature of occlusion, is affected significantly by posture.

This study was undertaken for the clinical analysis and evaluation on 121 patients with incompetent internal os of the cervix, who were admitted and treated with McDonald operation or Shirodkar operation at the Soonchounhyang Medical Center from January 1991 to December 1995. The results of this study were as follows : 1. The incidence of this IIOC was 1.1% of 11,116 cases of total delivery. 2. The mean age of IIOC was 31.7 years old. 3. The average number of gravida was 3.2. 4. The most common contributary factor was previous history of artificial abortion (51.2 %), and midtrimester abortion (17.4 %), cervical laceration due to previous vaginal delivery (8.3 %) etc. was followed. 5. The success rate of operation was 76 %, and the highest success rate (85.7 %) was reveald with period from 15th weeks to 16th weeks of gestation. 6. When cervical dilatation was abscent or small, the success rate of operation was high. 7. The factors of failed operation were preterm labor (58.7 %), PROM (34.5 %), and PIH, bleeding. 8. The delivery method after operation was vaginal delivery in 83 cases (68.6%) and cesarean section in 38 cases (31.4 %).

Intraorbital hydroxyapatite implant has advantages such as nondisplacement, prolapse and good prosthetic motility. The surgical effect of the secondary implantation of hydroxyapatite sphere was evaluated for 18 anophthairnic sockets of 18 patients. After follow-up period of over 6 months, extraocular muscle motility, prosthesis motility, improvement of the superior sulcus deformity, and enophthalmos were evaluated. Postoperative good EOM motility was noted in 7 cases (43.8%). Of the 15 cases without drilling, good prosthetic motility was noted in I case (6.7%), fair in 3 cases (20.0%), and poor in 11 cases (73.3%). One of the two eyes with drilling had good motility and the other one eye showed fair prosthetic motility. Superior sulcus deformity and enophthalinos improved in 12 cases-(75%) and 14 cases (82.4%). In postoperative complication, displacement or prolapse of the implant was not noted in any patient. and one patient. with postradiation showed m.inimal wound dehescence with spontaneous healing.

PURPOSE: Many patients complains of pain during shock wave lithotripsy(SWL). For this reason, SWL frequently is performed in decreased power setting of the shock wave and it could result in decreased fragmentation rate. We evaluated the fragmentation rates at different shock wave power in the same storage that resulted in the same amount of energy delivered. MATERIALS AND METHODS: From 1995 to 1997, a total of 97 renal stones less than 2cm in diameter were treated at the same sessional storage of 90 with various shock wave power(46%,54%,64%,74%,87%,100%). In case of EDAP device the energy delivered to disintegrate the stone is expressed as storage, that is calculated by power x duration x rate. The patients were treated by a power of 46 to 100 per cent at 10 impulses per second during the various treatment time to deliver the same storage. Complete fragmentation was defined as no residual fragments or fragments less than 3mm on KUB films at 2 weeks after treatment, otherwise another session was delivered. At 3 months after first session incomplete fragmentation was regarded as failure. Data were collected retrospectively and included the size of stones, the number of treatments and complete fragmentation rate. The results were compared between low power group at 46, 54, 64 per cent and high power group at 74, 87, 100 per cent of shock wave power setting. Statistical comparison were performed by the student`s t-test. RESULTS: The complete fragmentation rate was 74.2 per cent in 97 renal stones. The mean size of stones was 1.04+/-0.52cm and the mean number of treatments was 3.6 sessions. For low and high power group the mean size of stones were 1.10+/-0.62cm, 1.02+/-0.54cm, respectively(p>0.05) and the complete fragmentation rate was 50.0 per cent and 86.4 per cent, respectively(p<0.05). The mean numbers of session were 5.4+/-2.5 and 2.8+/-1.7, respectively(p<0.05). In cases of the complete fragmentation of stones the mean numbers of session between low and high power group were 5.2+/-2.3 and 2.3+/-0.6, respectively(p<0.05). Posttreatment complications, such as prolonged gross hematuria, perirenal hematoma or steinstrasse, was not seen in both groups. CONCLUSIONS: The above results indicate that the shock wave power is more important in fragmentation of urinary stone than the number of shock wave, even at same storage.
