Context: The total number of edentulous patients wearing mandibular implant overdentures is very less when compared to conventional dentures inspite of several advantages of mandibular implant overdenture over conventional complete dentures. Aims: This study aims to assess the awareness about mandibular implant overdentures among the edentulous patients who visit Vivekanandha Dental College for Women, Tiruchengode, Namakkal, using a questionnaire-based study. Materials and Methods: This questionnaire-based study is designed for the purpose of interviewing 300 consecutive edentulous patients. These patients have visited the Outpatient Department of Prosthodontics of Vivekanandha Dental College for Women, Tiruchengode, Tamil Nadu, between September 2015 and January 2016 extending for a period of 5 months. Statistical Analysis Used: Chi-square test and Fisher's exact test. Results: The level of awareness about implant-supported mandibular overdentures was significantly less among the edentulous patients visiting Vivekanandha Dental College for Women in Namakkal district. Conclusions: Almost less than one-fourth of the edentulous population are aware of implant-supported overdentures, and nearly 71% of the population were not informed about this treatment option by their dentists, media, or friends which clearly reinforces the need for proper provision of information by the dentists to the population so that the awareness about dental implants reaches the unreached.

| Introduction|| |
The treatment of edentulism with traditional removable dentures is less accepted due to many factors such as anatomical, physiological, psychological, and prosthodontic factors. Implant treatment has provided excellent long-term results by increased retention, stability, functional efficiency, and quality of life.,
The success rate of implant-supported crowns in partially edentulous patients was estimated to be between 96.6% and 98.5%.,,,, The successful use of dental implants in the treatment of edentulous arches has been confirmed in various clinical studies [Figure 1].,,
For practicing dentists, it is imperative to know whether today's patients are aware of dental implants as a treatment option and whether the information that they have is close to reality. Awareness among patients regarding the procedure can help in eliminating any negative image of the procedure that may have been caused due to lack of adequate communication. The right kind of information, if channelized to the patients correctly, will further help in promoting this superior treatment as a treatment option among the patients.
| Materials and Methods|| |
An epidemiological study was conducted to access the level of awareness among 300 edentulous patients in Namakkal district. A self-explanatory questionnaire was designed to assess the patient's knowledge and awareness about mandibular implant overdentures. The questions were validated by circulating them among the prosthodontists in the hospital. The questions were then circulated among the 300 consecutive patients visiting the Outpatient Department of Prosthodontics in Vivekanandha Dental College for Women, Tiruchengode, Namakkal district, Tamil Nadu, between September 2015 and January 2016 for a period of 5 months. The patients included 132 females and 168 males. The minimum age of the patients was 32 years and the maximum age of the patients was 80 years. The responses given by the patients were analyzed statistically and the results were concluded.
| Results|| |
The minimum age of the patients who were examined is 30 years and the maximum age for the patients is 80 years [Table 1]. The mean age is around 58 years. The number of male patients examined is 169 and the number of female patients examined is 131.
The awareness of the population was found to be statistically insignificant at a P value of 0.873, which indicates that the awareness is very less among the edentulous patients who visited Vivekanandha Dental College for Women in Namakkal district. The awareness about this treatment procedure among the male and female patients indicates that of the 131 female patients who were examined, only 43 females (32.8%) were aware of the treatment option and of the 169 male patients, only 54 males (32%) were aware of the procedure. From the results, we can see that the awareness is significantly low in this locality with no significant difference between the male and female population. The remaining 67.7% were totally unaware of the treatment procedure [Figure 2]. Thus, among the 300 patients who were questioned, only 97 were aware and the rest 203 patients were unaware about the treatment option [Table 2].
Source of information
When the source of information of these 32.3% of the patients who were aware of the treatment option was analyzed, it was found that among the 97 patients out of 300 who were aware about mandibular overdentures, only 42.3% of them came to know it through the dentist. Another 54.6% received the information from friends and family. The rest 3.1% of the population knew it through the media [Table 3] and [Figure 3].
Patient's willingness for the treatment
After the explanation of the treatment procedure, almost 194 patients (64.7%) out of 300 patients were willing for the treatment. Only 106 patients (35.3%) were not willing to take up the treatment [Table 4].
Reason for denial
Of the 106 patients who were not willing for the treatment, nearly 67 patients (63.2%) were not willing for the treatment due to fear and confusion [Table 5]. Only 36.8% of the population were unwilling for the treatment due to cost factor [Figure 4].
| Discussion|| |
Implant dentistry has become the most common and successful treatment procedure in the current dental practice and has become the elite choice for replacement of missing teeth. A study conducted by Grogono et al. has proved that the patients who underwent implant treatment procedures had a considerable increase in their level of self-confidence and oral health levels and were willing to undergo the treatment procedures again. However, the awareness about the implant procedure and its success is still meager in the developing countries. This is confirmed by a survey conducted by Chowdhary et al. in the year 2010 in the Indian urban population, which concluded that only 23% of the Indian urban populations were aware of dental implants.
On searching the literatures for studies in the topic of awareness about mandibular implant-supported overdentures, it was found that the researches are very few, and hence, this study has aimed in fulfilling this defect.
The findings of this study are lower than studies conducted by Zimmer et al., Berge, and Tepper et al., which reported the level of awareness as 77%, 70.1%, and 72%, respectively. This might be due to low socioeconomic status and low education level among the study population. Furthermore, the awareness level was not significantly different for males and females. A similar study conducted by Kranjcic et al. (2015) in the Croatia population reported the awareness level to be 59%, with slight variation based on age, education level, and gender. Younger male patients and people with higher educational qualification showed more awareness.
In this study, the patients are examined face to face by the same examiner, and hence, the results though time-consuming and exhaustive are more accurate when compared to the other methods of data collection such as using many examiners, mails or handouts, or phone interviews. All patients in this study are selected consecutively in the order they visited the Outpatient Department of Prosthodontics of Vivekanandha Dental College for Women, Tiruchengode, Namakkal, thereby eliminating errors due to bias.
Regarding the source of information about implant overdentures, the findings of this study match with Akagawa et al.'s study (1988), which concluded that dentists provided not more than 20% of the information. The findings of this study match with many other findings conducted in different parts of India and other places.
Almost 51% of the patients who were questioned about the need for hospitalization thought that hospitalization is needed, and nearly 50% of the patients thought that the implant-supported overdentures can lead to significant adverse effects. These results were similar to the findings by Al-Johany et al. who said that despite the comparatively high level of awareness of dental implants, only 49.9% of those questioned correctly cited the jawbone as the host site for implants, which reveals incomplete or incorrect information about dental implants even when being aware of this treatment option.
The main drawback the patients faced with the conventional mandibular dentures was lack of retention, and the main expectation of the patients who were willing for the treatment was adequate retention and stability of the dentures. Hence, by creating awareness among the people regarding the implant-supported overdentures, we can satisfy their need for adequate retention and stability with the mandibular dentures. This problem of lack of awareness is more magnified in the developing countries due to lack of effort taken by the dentists and the concerned authorities in educating the people about dental implant treatment options. The findings of this study are in agreement with various other studies conducted in different parts of India which include Jaipur, Bhopal, Indore, Ahmedabad, and Chhattisgarh.,,,,,
A similar study conducted by Raghoebar et al. compared retention, esthetic satisfaction, comfort, and ability to eat and speak between patients wearing implant-retained removable dental prosthesis and conventional removable partial dentures and found that the implant-supported overdentures were a favorable treatment modality among the edentulous patients. Thus, all these studies should be a stimulation for dentists to educate their patients about dental implants and treatment modalities, individually in their practices or even through organized lectures in various elderly care homes and other public places.
| Conclusions|| |
Majority of the patients are unaware of mandibular implant overdentures as a substitute for replacement of missing teeth. Dentists are found to provide inadequate source of information to the patients, and hence, dental health education involving dentists should be utilized for effective circulation of information to create awareness toward implant treatment.
Lack of awareness and fear are identified as main barrier for undergoing implant treatment and high cost is identified only as a secondary factor. Dentists should be actively involved in creating awareness not only among the patients who are visiting the clinics and hospitals but also among the general public through the organization of camps, distribution of pamphlets, utilization of media, and publication of journals and articles which could reach the public.
These steps can convince more and more patients on taking up implant-related treatment options and benefitting from it. Thus, the field of dentistry can be taken to the next level in our country.
