Introduction: The total convergence of the axial walls is the angle made between the opposing axial walls of an abutment. The lower the taper value, the better the retention of the crowns is. Obtaining a proper convergence of the axial wall is a challenge for dental practitioners due to limited access and low visibility, but it also greatly depends on the clinician’s practical skills.

This study aims to compare the total convergence of axial walls obtained after tooth preparation done by different experience practitioners in various positions of the patient and different working time (different days of the week, various parts of the day).

Materials and methods: To perform this study, 40 acrylate model teeth have been prepared by two last year dental students and two prosthetists. All of them performed two teeth preparations per day in every working day of a week. All the prepared teeth have been photographed, and digitally measured.

Results: The extremely statistically significant difference was found in the two beginners’ case, the values of the second beginner being much higher, as in the two experienced operators, where the values are higher for the second prosthetist.

Conclusion: The total convergence of the axial wall did not depend on the operators’ experience or education level.


Introduction: Edentation is a major emergency and has an echo over the entire stomatognathic system. The treatment of partial edentation has undergone major changes in the last decades for multiple causes, including increasing the level of dental, medical education, introducing new techniques, methods, and materials, increasing the duration of retention of teeth on the arch.

Aim of the study: The aim of this study is to determine the degree of satisfaction of patients with a fixed prosthetic denture, to highlight the importance of communication between doctor and patient with repercussions on the results of prosthetic treatment, and evaluate the degree of awareness of oral health and oral hygiene practices.

Material and Method: For this study it was used a self-designed questionnaire, which explored both clinical and non-clinical dental services. The questionnaire consisted of three parts: first part (A) includes socio-demographic indices, part two (B) includes questions related to the doctor-patient relationship, and in the third part (C) the questionnaire asks questions regarding the general satisfaction of the patients with reference to the prosthetic tratament. The questionnaire also includes the material (s) from which the prosthetic denture is performed and the area of the edentation.

Results: The present study was performed on a batch of 117 people, 48 female, and 69 males between the ages of 21 and 60. Our results show that the majority of patients present metallic-ceramic dentures, located in most cases in the lateral area, and the majority of patients are satisfied with the prosthetic tratament. There were no patients complaining about the result of the tratament. Pacients are delighted by their relationship with medical staff.

Conclusions: The most important finding of this study states that a large proportion of patients showed a lack of knowledge regarding oral hygiene measures and the importance of maintaining a fixed prosthetic denture using a dental abutment. Also, the majority of the doctors did not pay attention to the post-treatment instructions regarding the maintenance of a fixed prosthetic denture.
