## 4 Discussion  
The present study aimed to evaluate the quality of communication between dentists and dental technicians via work authorization for fixed and removable dental prostheses in Pakistan. The questionnaires used in the study were designed using binary scales rather than traditionally used ordinal multi-category answer formats (such as the Likert scale). This was performed to reduce respondent fatigue and increase the response rate and data quality by making the questionnaires short, precise, and reader-friendly [18]. Communication between dentists and dental technicians is of paramount importance, as the success of a dental restorative treatment depends on it. Dentists are equipped with the knowledge and skills to guide dental technicians regarding the patient's functional habits and aesthetics to achieve an optimal restoration for the patient. The design of an RPD also has an important role in the health of the dental and periodontal tissues and the stability of the denture [19; 20]. Hence, it is the responsibility of the dentists to guide the dental technician in the design and construction of a dental prosthesis without delegating their responsibilities to the technicians. In the present study, the majority of the dentists (92.1%) left the designing of the dental prosthesis to the technician. However, it is the dentist who has knowledge of the biological factors, pathological processes, and possible influence of mechanical factors on the masteratory system. In addition, the dentist has the ability to modify the oral environment to increase the effectiveness of an RPD treatment (e.g., by tooth preparation or periodontal or orthodontic therapy). The findings of this study suggest either a lack of knowledge and ability from the dentist in designing partial dentures or their dependency \begin{table}

Figure 2: Satisfaction with the restoration design by the dentists (\(n=453\)). on the technicians. It has been suggested in previous studies that interns and dentists are not able to adequately design removable partial dentures [21]. The primary reason behind the lack of ability to design a denture lies in the poor knowledge, experience, and attitudes toward it [22]. However, a study by [PERSON] et al. disagreed with the present study, where it was found that most of the dental technicians believe that the responsibility of designing the dental prosthesis is the dentist's [10]. Moreover, a lack of emphasis on laboratory work during the undergraduate study period can also be a contributing factor to the lack of knowledge on designing a dental prosthesis. As stated by [PERSON], the design of any prosthesis is based on mechanical and biological principles [11]. Inadequate communication of the design information results in a prosthesis that has been fabricated with little reference to important clinical or biological information [3]. Hence, communication between the dentist and dental technician or having complete information provided with the impression is a very important step.
