Abstract
Purpose: To analyse the esthetic appearance of a new ceramic implant in the anterior maxilla and to assess the students’ and laypeople’s ability to identify the implant in the mouth. Furthermore to analyse the satisfaction of patients regarding their implant esthetics over various periods of time. Methods: Twenty patients were included in the present study. Inclusion criteria: a flapless, immediately placed Zirconia implant. Two measurements were set for evaluation of the esthetics: one measurement directly after placement of the final crown and one measurement further in time. The second measurement was divided into three arms: 1. 0,5-3 years, 2. 3 – 5.5 years and 3. 5,5 – 8 years. The Pink Esthetic Score (PES) and the White Esthetic Score (WES) for both measurents were evaluated through photographs taken in maximal occlusion. The mean PES and WES results were calculated. The statistically significant differences between measurement 1 and measurement 2 were calculated The significant statistical differences between measurement 1 and 2 were calculated for the whole study population and separately for the three separate groups (pared t-test, P<0,05). Furthermore 20 photographs from the included patients, taken at the first measurement, have been shown to 40 volunteers (20 laypersons and 20 dentistry students). They had 30 seconds to identify the implant in the photo. The percentage of non-identified implants and the difference between layperson and students was calculated (unpared t-test, P<0,05). A questionnaire with Visual Analogue Scale questions (VAS) concerning the esthetic perception of the implant was given to the included patients. The possibility of a correlation between the VAS-questionnaire and the PES/WES was investigated. Results: The PES has a maximum score of 14 and the WES has a maximum score of 10. The higher the score, the better the esthetic outcome. The PES/WES results from 20 patients were evaluated. The first measurement showed a mean PES of 12,8 (range, 11 to 14) and a mean WES of 8,5 (range, 2 to 10). The second measurement showed a mean PES of 12,8 (range, 8 to 14) and a mean WES of 8,6 (range, 6 to 10). Tests concerning the entire study population showed no statistically significant difference between measurement 1 and measurement 2. Within arm 1 a statistically significant difference was found between measurement 1 and measurement 2. Out of 40 volunteers, 74% laypeople and 56% the students did not recognize the implant correctly. Students were statistically significant better at recognizing the implant in the mouth. Eightteen of the 20 patients filled in the questionnaire, the mean assessment of esthetic satisfaction is 8,5 on a 0 – 10 point scale. No correlation was present between the outcome of the VAS-questionnaire and the PES/WES. Conclusion: The PES/WES scores of the new Zirconia implant range from good to optimum and they are even better than previously described in literature. There is no statistically significant reduction of the PES/WES in a period of 8 years after placement of the permanent crown. It was shown that a high percentage of laypeople and students are not able to identify the implant in the mouth. Students are significantly better at recognizing the implant. Regarding the esthetics, patients are very satisfied with their implant.
