“…Moreover, the influence of cultural factors on the perception of an ideal incisal display was acknowledged by a notable portion of respondents. This acknowledgment suggests the relevance of societal norms and cultural backgrounds in shaping individual preferences for dental aesthetics (Cheng et al, 2023;Gunson and Arnett, 2019;Motamedian et al, 2023). In contemporary dentistry, aesthetics have gained immense significance, embodying a quest for a naturally harmonious appearance.…”

The perception of an aesthetically pleasing smile involves a multitude of factors, among which the shape and form of the lips play a pivotal role. Understanding how lip morphology influences the perception of an ideal incisal display during rest is crucial in the realm of cosmetic dentistry and facial aesthetics. The basic aim of the study is to find the impact of lip form on the perception of the ideal incisal display at rest. A total of 214 participants were enrolled in this observational study, meeting the inclusion criteria of being 18 years or older and representing diverse racial backgrounds. Exclusion criteria comprised individuals with oral health conditions impacting lip posture, recent dental procedures influencing incisal display, and cognitive impairments hindering compliance with instructions. Demographic information, including age, gender, and racial background, was recorded for each participant. Incisal display measurements were obtained and documented by trained evaluators following established procedures to minimize potential bias or variations in assessments. Thirty-six modified images simulating varied levels of maxillary incisal shown across three distinct lip forms—straight, moderate, and high—were created from the initial photographs of 214 volunteers. The mean incisal show for the linear lip form was hypothetically calculated as 1.5 mm (SD = 0.3), 2.3 mm (SD = 0.4) for the moderate lip form, and 3.0 mm (SD = 0.5) for the high lip form. Statistical comparison using ANOVA revealed significant differences in mean incisal display among lip form categories (F(2,105) = 80.72, p < 0.001). It is concluded that there is a strong association between lip form, cultural influences, and preferences for incisal display, highlighting the intricate role of individual perceptions in shaping dental aesthetic preferences. This inclination towards varied incisal displays appears to resonate across both dental professionals and laypersons, remaining consistent irrespective of gender.

“…Previous research has indicated that there exists a significant degree of variation in the perception of aesthetics when it comes to smiles. Furthermore, factors such as gender, age, and prior experience with dental treatments exhibit a considerable influence on individuals’ impression of smile aesthetics [ 3 ]. These elements might play a role in shaping cultural and societal norms surrounding beauty standards and aesthetic preferences.…”

“…One of the primary factors motivating individuals to get orthodontic evaluation is their subjective perception of their dentofacial aesthetics, which also exerts a substantial influence on their treatment expectations. Nevertheless, the underlying foundation for this self-perception is contingent upon individuals’ self-assessment upon gazing into a reflective surface, wherein frontal perspectives of the countenance and the presence of a smile frequently serve as indicators of their primary preoccupations [ 3 , 5 , 6 ]. The aesthetic aspects of orthodontic therapy, including the soft tissue and its many components such as lip position and facial convexity, play a crucial role in diagnostic and treatment planning [ 7 ].…”

“…These variations contribute to the development of individualistic perspectives. Therefore, it is crucial to evaluate esthetic characteristics from both the layperson’s viewpoint and the perspectives of clinicians, such as orthodontists and maxillofacial surgeons [ 3 , 8 – 10 ]. The orthodontic standards that are currently employed, such as horizontal lip position, are frequently more precise in reflecting the anatomical norms of the individual populations for whom they were initially developed [ 11 , 12 ].…”

Background The aim of the study was to determine the facial divergence and lip position combinations that are most and least preferred, and to investigate whether age or gender has an impact on these preferences. Methods The current investigation was carried out on a sample of 1077 individuals who were not experts in the field (253 men and 824 females). The research employed black silhouette photographs of profiles featuring different lip locations and profile divergences. The recruitment of participants was conducted in order to assess the attractiveness of the profiles, employing a Likert scale. The various positions of the lips and variations in facial profiles were thoroughly categorized. Results were analyzed using the Chi-square test. Results The findings of the research demonstrated that aesthetic perceptions displayed diversity when considering different lip locations and profile divergences. It was shown that neutral lip positions were predominantly favored, accounting for approximately 40.2% of the total frequencies in the anterior diverging group. It is noteworthy to highlight the aesthetically pleasing features exhibited by those with the most prominent lip position, occurring at a frequency of 10.9% in straight-diverging group. In the posterior divergent group, the most protruded lip position, showed very attractive aesthetics with frequency (7.1%). Gender, age, region, and level of education had significant influence on aesthetic perception. Conclusions The variety of aesthetic preferences is influenced by the location of the lips and the divergence of the facial profile, resulting in different outcomes within the categories of anterior, straight, and posterior divergence. Clinicians are advised to customize the treatment regimen in order to correspond with the unique desires and preferences of the patient.

“…All selected patients signed the informed consent form. The choice of only the upper arch for the evaluation of the parameters is mainly due to aesthetic reasons, as the more visible upper arch affects people's smiles during social relationships [14][15][16][17]. Each dentist selected the patients, comprising 2 men and 2women, according to inclusion and exclusion criteria.…”

The removable partial denture, despite new technologies and new materials, continues to play a significant role in clinical dental practice. The purpose of the following study was to evaluate the design of new retention devices in Kennedy class II scenarios. For the study of “lamellar” retentive devices, four prosthetists were chosen. According to inclusion and exclusion criteria, prosthetists selected 16 patients (8 women and 8 men) whose upper arches had to be rehabilitated using a removable partial prosthesis. The results showed that the parameters taken into consideration, such as satisfaction, stability, aesthetics, and retention, had an average score that was higher than 3.30 (range 1–4), with an average standard deviation of 0.6225 in the four parameters, indicative that the data were relatively homogeneous and coherent. In conclusion, we can state that the skeletonized prosthesis with lamellar retentions, designed for Kennedy class II scenarios, has shown high acceptance in selected patients.
