A qualitative twitter analysis of the patient experience with invisible orthodontics; lingual braces versus invisalign

Objectives: The aim of this qualitative study was to examine orthodontic patients’ thoughts and experiences about the invisible orthodontic treatment options – lingual braces and Invisalign – through the analysis of Twitter posts’ content. Materials and Methods: A software program was written for the data collection. The program consecutively collected the tweets posted over an 8-month period from Twitter’s publicly accessible database. Tweets that were written in the English language and contained any of the four keywords “Invisalign,” “lingualorthodontics,” “lingualbraces,” and “invisiblebraces” were collected. The tweets that included irrelevant or incoherent posts, professional advertisements, unclear/not applicable content, and reposts were excluded from the study. Two authors, with different experiences, independently read, and analyzed the tweets. Each applicable tweet was classified into one of the three categories: Positive, negative, and neutral for two study groups (Invisalign and lingual braces). Pearson Chi-square test was used to analyze the negative and positive tweet rates of the groups. Results: 1176 of 2407 tweets were selected as applicable and analyzed by the authors. There was a statistically significant very good agreement between the two observers (Kappa = 0.933, P < 0.001). The negative comment rate (39%) and neutral comment rate (31.1%) in the lingual group were statistically higher than the Invisalign group (27.2% and 21.7%, respectively; P < 0.001). The positive comment rate in the Invisalign group was significantly higher (51.1%) compared to the lingual group (29.9%, P < 0.001). Conclusion: Orthodontic patients use social media to share their experiences and feelings about their treatment process. The applicable Tweet number and the positive Tweet rate in the Invisalign group were higher than the lingual braces group.
