a new fixed-partial denture design using laminates is described for the replacement of a missing anterior tooth. in this article advantages, disadvantages, indications and contraindications of the new design have been discussed. this method is best suited for cases with missing incisors and esthetically compromised abutment teeth.

careful treatment planning, space management, augmentation of bone and attention to the details of implant surgical and prosthetic techniques are important factors when treating anterior maxilla, especially in the replacement of missing teeth. this case report addresses the fundamental considerations related to replacement of a congenitally missing lateral incisor by a team approach.

Evaluation of performance and productivity is among the fundamental concepts inmanagement. In order to achieve their goals, organizations must evaluate theirperformance. One of the important stages of performance appraisal is evaluation oforganization’s efficiency. Banks, financial and credit institutions are among the mostimportant organizations of every economic system, because every activity...

There are several methods to make inferences about the parameters of the sampling distribution when we encounter the missing values and the censored data. In this paper, through the order statistics and the projection theorem, a novel algorithm is proposed to impute the missing values in the multivariate case. Then, the performance of this method is investigated through the simulation studies. ...

Conventional data envelopment analysis (DEA) models normally assume all inputs and outputs are real valued and continuous. However in problems some inputs and outputs can only take integer values, also, both desirable and undesirable outputs can be generated . In this paper the effect of undesirable outputs in integer DEA model is discussed. The proposed model distinguishes weak disposability o...

The most common congenital and developmental anomaly in teeth is the missing of one or more of them. Congenitally missing teeth (CMT) or teeth agenesis mentions failure of tooth formation due to disturbances during the early stages of tooth germ development. There are several definitive treatment options for these patients including fixed, removable or implant-supported prostheses. Economic lim...
