When fabricating definitive implant-supported fixed prostheses in upper and lower completely edentulous patients, it is crucial to get information about the vertical dimension, jaw relationship, implants, abutments and gingival contour.In this case, temporary prostheses were used to take the information. The temporary prosthesis was scanned outside of the mouth so that it increased the efficiency of scanning it. During the scan of the prosthesis, a scan zig which connected both posterior parts of the prosthesis was used to minimize the scan errors. We report this case because we obtained satisfactory functional and esthetic results by using the digital technology.

Spasticity is a wide variety of motor problems to connote difficulty with coordinated movements, involuntary spasma, rigidity. Abnormal primitive reflexes and hyperactive reflexes. Electrophysiologically, spasticity is represented as the involuntary firing of motor units on a reflex basis at a polysynaptic spinal cord level, associated with interruption of descending cortical pathways. Although many procedures have been tried over the years to combat this spasticity, and the multitude of procedures indicates that none are entirely satisfactory, the reduction in spasticity produced by dentatotomy has been confirmed in many neurological centers. The F-wave is a late response recorded in the electromyography of a muscle following stimulation of its nerve supply. There is evidence that the size of the F-wave is dependent on motor neuron excitability. If such a relationship exists, procedures which are carried out to relieve motor neuron excitability might be expected to change F-wave size and it might therefore be possible to use the F-wave as an objective monitor during stereotactic dentatotomy. We have investigated this possiblity in 10 cats, weighing 2.8 to 3.7kg each. The size of F-wave Amplitude in experimental animals were devided into 2 groups, normal control group values(10 cats, before dentatotomy) and the dentatotomy group values(10 cats after dentatotomy). The F-wave size and F/M ratio were recorded from right tibialis anterior muscle after application of supramaximal stimulation(250 V. 100 mA. 2 Hz. 10 times) on the right peroneal nerve. The results were as follows: 1) The size of M-wave amplitude did not change significantly in experimental models(before dentatotomy, 2805.5+/-1012.3 microV;dentatotomy group, 2555.5+/-725.9 microV, P>0.05). 2) The individual size of F-wave showed a wide variability from each stimulus, which emphasizes the importance of using 0 stimulating responses. The mean value of F-wave amplitude before dentatotomy was 436.5+/-113.2microV. 3) The size of F-wave amplitude was significantly reduced after dentatotomy(before dentatotomy, 436.5+/-113.2microV;after dantatotomy: 212.5+/-49.3microV, P<0.05). The size of F-wave amplitude decreased about 48.6% after dentatotomy. 4) The F/M ratio also significantly reduced after dentatotomy(before dentatotomy, 17.1+/-6.6%;after dentatotomy, 8.5+/-1.2%, P<0.05) and mean reduction was 49.7%. The results demonstrated that the dentatotomy markedly decreased the size of F-wave amplitude in experimental cats and indicated that the monitoring of F-wave amplitude during dentatotomy might be useful as an objective monitor for the relief of spasticity.

Before surgery for hemorrhoid, patients always have a worry of postoperative recurrence. The exact incidence and risk factors of recurrent hemorrhoid have not yet been delineated up to now. Therefore, the aim of this study was to assess the etiology of the recurrence after surgery. MATERIAL AND METHODS: Between March, 1997 and Feburary 1998, all patients who visited the Dept. of Surgery, Korea Veteran Hosipital, due to the recurrent hemorroid after surgical managememt including sclerotherapy(Group II: GII, n=60) were compared to the age and sex mathed(1:2) with primary hemorroid patients(group I: GI, n=120). The risk factors which might be related with the recurrence such as 1) hemorroidal factor(duration of symtom, symtom, associated perinial disease) 2) patient factor (constipation, incontience, cardiovascular disease, pulmonary and hepatic disease) 3) anorectal physiologic factors 4) surgical factors were evaluated. Stastical analysis were performed by a chi-square-test or Mann-Whitney U test and set the significance at p<0.05. RESULTS: There were no differences between the two groups in terms of age(GI 58.1+/-8.5, GII 60.9+/-3.3 years), gender(M:F, GI; 97:23, GII; 56:4 ). The ratio of having a contipation before surgery was 41% in GI, 55% in GII. It was not statistically significant. However, the other factors related with constipation such as duration of constipation(GI; 9.85+/-7.73 years, GII; 14.62+/-7.38 years: p<0.05), duration of straining during defecation(GI; 5.82+/-2.34, GII; 7.32+/-5.6 minutes, p<0.05) number of laxative use(GI; 29, GII; 28) were significantly different between the two groups. The fecal incontince are 5% in group Iand 13% in group II. There were no differences in patient's subject symtoms related with hemorrhoid, and comorbid perianal disease between the two groups. In anorectal manometric findings, rectal complince was significantly lower in GII than that of GI(25.1+/-50.04 cc/cmH20 vs 16.0+/-25.2 cc/cmH20 p<0.05). GII has a significant number of preopertive hypertension than GI(6.7% vs. 21.6%, p<0.05). CONCLUSION: When a patient with hemorrhoid has a constipation or hypertension, and lower compliance in manometric findings, it would be related with the postoperative recurrence after treatment. Therefore, we surgeons should correct these comorbid conditions before surgery, otherwise give an information to the patient of high chance of postoperative recurrence after management.
