This article introduces a new concept,named “dynamic functional design”(DFD)for the anterior guidance control of prosthe-ses.The concept was proposed from the deficiency of “digital smile design”as a complement.Four key points have been discussed to realize DFD in clinic by 1 0 real cases,and a new classification for anterior teeth restoration is presented according to DFD in this paper.

This article introduces the origin of articulator and its development process from humble to perfect in the past more than 200 years. The development of articulator is divided into 3 historical periods by the author:Early articulator,modern articulator and contemporary articula-tor.Meanwhile,the detailed basic design principle of articulator,the development of condylar guidance and incisal guidance are explained.

The presented article introduces a new classification based on the definitive condition of “Occlusion”after repair for different dentition defects,edentulous jaws and maxillofacial defects.The new classification contains 2 types and 8 subclasses descriptions.Exquisite pictures are used for the detailed demonstration.It may help dentists to know the final occlusion result even before the treatment and to pre-pare the major clinical operations..

With the wide application of digital technique in dental clinic,the virtual articulator has become an important tool of CAD/CAM systems for dental labs.The presented article introduces the classification,advantages and setting parameters of the virtual articulator.The authors also comment on the current commercial products of the virtual articulators in the domestic market.

This article systematically introduces the basic conception,classification and physiological significance of anterior guidance for anterior prostheses.A customized incisal guidance table was introduced to record and transfer the individual value of the patient to a virtual full-adjustable articulator system.The clinic effects of the individual value and average value were also compared.

With the development of implant,more reliable way of the treatment of posterior teeth loss can be acheived.Dental implants present different biological and biomechanical characteristics from natural teeth and natural teeth with crown.It is important to realize these differences and occlusal adjustment accurately for the improvement of the treatment and prolongation of implant service life.This paper re-views the critical point with a clinical case.

This paper reports the nursing experience of 5 cases of Charcot's arthropathy undergoing rotating hinge prosthesis knee replacement. The nursing care focused on psychological nursing, preoperative examinations, control of blood glucose and treatment of syphilis during preoperative period, as well as wound care, management of drainage tube, prevention of complications and early functional exercise during the postoperative period. All cases were followed up through 6 to 60 months. The short-term outcomes were satisfying. One patient suffered from periprosthetic femoral fracture at 23-month after the operation, and healed up eventually after open reduction and internal fixation.

Objective To explore the clinical application of reconstructing silicone elastomer nose prosthesis by means of selected laser sintering and wax powder PCPI. Methods Laser scanning was used to get the 3-D data of a nose model. Surfacere 10.0 etc softwares was used to reconstruct the nose by mirroring the digitalized model of absent nose. Selective laser sintering and wax powder was chosen to fabricate a wax nose model and the nose prosthesis made by silicone clastomer. Results Perfect silicone clastomer nose prosthesis was made for 2 patients. Conclusion This study suggests that the wax nose model and the new wax powder can meet the requirement of clinical expectation for maxillofacial prosthesis.

Objective:To estimate the clinical effect of integrated Xinjia Shashen Maidong Decoction and radiotherapy on advanced non-small-cell lung cancer (NSCLC) patients.Methods:30 NSCLC patients were treated with Xinjia Shashen Maidong Decoction after radiotherapy for more than two months,then the clinical effect were evaluated by tumor-mass stable rate,symptoms,Karnofsky score and survival period.Results:Response Evaluation Criteria in Solid Tumor (RECIST) evaluation results showed that the effective rate on relieving tumor mass was 53.3%,stable rate was 86.7%.The symptom of cough was much relieved,with 56.7% effective rate and 93.3% stable rate.And effect on Karnofsky score was good,that effective rate was 56.7% and stable rate was 86.7%. Fortunately,the patients had a median survival period of 11 months.Conclusion:Xinjia Shashen Maidong Decoction enhanced the efficacy of radiotherapy and reduced its side-effects in the treatment of advanced NSCLC patients.

Objective: To test the reliability of 3 dimentional (3D) laser surface scanner for nasal anthropometry.Methods:11 plaster nasal models were measured by 3D laser surface scanner and manual measurement. The data were statistically analyzed. Results:In 9 out of the 10 parameters of nasal anthropometry,the correlation coefficient of the distances and angels measured by the 2 means was 0.856-1.000(P
