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..

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.

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.

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 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.

Objective To investigate the related factors of central nervous system infection in patients who received invasive intracranial pressure monitoring.Methods The clinical data of 63 patients who received invasive intracranial pressure monitoring were retrospectively analyzed.Possible related factors including gender,age,disease,Glasgow coma scale score,emergency operation or selective operation,duration of the operation,drainage tube placement site,drainage tube lifetime,sensor insertion site,sensor indwelling duration,electrolytes,glucose and other complications were studied and compared retrospectively between patients with and without central nervous system infection.All data were analyzed with univariate analysis and multivariate Logistic regression analysis to identify the related factors and independent risk factors associated with central nervous system infection.Results In univariate analysis,drainage tube placement site (x2 =12.345,P =0.002),drainage tube lifetime ((2.5 ± 0.9) d and (6.3 ± 5.7) d in patients without and with central nervous system infection,respectively,t =-4.434,P =0.000),sensor insertion site (x2 =4.701,P =0.030),sensor indwelling duration ((6.5 ± 3.0) d and (8.9 ± 4.6) d in patients without and with central nervous system infection,respectively,t =-2.420,P =0.019) and other complications (x2 =13.086,P =0.000) were the relevant factors of central nervous system infection (P ＜0.05).In multivariate Logistic regression analysis,the sensor insertion site (OR =0.047,P =0.000) and other complications (OR =10.953,P =0.019) were the independent risk factors for the central nervous system infection.Conclusions There are a variety of factors related to central nervous system infection in patients with placement of intracranial pressure monitoring.The sensor insertion site and other complications were the independent risk factors for the central nervous system infection.

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

Objective:To build 3D digitized face model of unilateral orbital defect and to realize imitating design of defect section.Methods:Phase measuring profilometry was employed to acquire a 3-D digitized face model with open eyes.By Geomagic software,the image of normal orbit was extracted and mirrored with the image of the deformed side of the orbit.Results:A 3-D digitized face model of unilateral orbital defect was successfully reconstructed and 3-D normal orbit data of defect section was acquired.Conclusion:The use of phase measuring profilometry and RE software is a convenient and effective method to the computer-aided design for the restoration of unilateral orbital defect.
