“…In our analysis, we observed lower impact values for all quality-of-life domains in the lingual bracket group ( Table 3 ). We did not find statistically significant differences in terms of functional limitation (speech and chewing); however, other authors consulted found that speech and pronunciation were affected by lingual appliances [ 19 , 20 , 21 , 46 , 56 ]. A total 23.3% of patients with lingual brackets were found to still have difficulties with their pronunciation after three months [ 46 ].…”

“…According to most authors, self-ligating brackets produce less pain and have less impact on the oral quality of life than conventional fixed orthodontic treatment [ 8 , 12 , 13 , 17 , 18 ]. Regarding lingual orthodontics, most authors consider that there is greater pain and impact on function (speech and chewing) in these patients compared with users of conventional orthodontics; however, aesthetics are improved [ 19 , 20 , 21 ]. This improvement in the perception of aesthetics and comfort by patients has also been observed in users of the Invisalign system, with a lower perception of pain from the second day onwards when compared with patients treated with conventional orthodontics [ 14 , 22 ].…”

The aim of this study was to compare pain and its relationship with the oral quality of life of patients with different types of orthodontic appliances: conventional and conventional low-friction brackets, lingual brackets, and aligners. A prospective clinical study was carried out with a sample size of 120 patients (54 men, 66 women) divided into 4 groups of 30 patients each. The modified McGill questionnaire was used to measure pain at 4, 8, and 24 h and 2, 3, 4, 5, 6, and 7 days after the start of treatment, and the Oral Health Impact Profile-14 (OHIP-14) questionnaire was used to measure the oral-health-related quality of life (OHRQoL) in the first month of treatment. The maximum peak of pain was obtained between 24 and 48 h of treatment. It was found that patients in the lingual orthodontic group described lower levels of pain at all times analyzed, and their scores in the total OHIP-14 indicated less impact on their oral quality of life (1.3 ± 1.2, p < 0.01) compared with the other groups analyzed. There was little difference with the aligners group (Invisalign) (1.7 ± 1.9, p < 0.01). The technique used influences the pain and quality of life of patients at the start of orthodontic treatment.

“…The result suggests that in producing velar sound, the tongue can adapt a very short time of period. Similar finding were also noted by Haydar et al [7] and Rai et al [17]. On the second week of retainer wear (T 3 ), there was a statistically significant transition of /t/ sound to normal pattern (p>0.008).…”

Background: Orthodontic retainers constrict the oral cavity's dimension and restrict tongue movement during articulation, resulting in distortions of various sounds. Speech impairment is among the main reason for poor patient compliance in wearing the retainers which leads to treatment relapse. Objectives:To determine and describe the changes of the distorted sounds in patients wearing upper and lower Hawley retainer. Materials and methods:Sixteen orthodontic patients who were at the end of fixed appliance phase were included as subjects in this study. They were all speakers of native Malay, aged between 15 to 31 years old. The sound sample of selected phonemes with /t/, /d/, /k/ and /n/ consonant were recorded from the subjects before wearing (T 0 ), immediately after wearing retainers (T 1 ), and at 1 week (T 2 ), 2 weeks (T 3 ), 1 month (T 4 ), 2 months (T 5 ) and 3 months (T 6 ) of wearing the retainers. Based on the recordings, acoustic analysis was performed objectively on each subject to determine the duration value of selected phonemes at each interval.Results: All phonemes tested showed significant speech distortion (p<0.008) immediately after wearing the retainers. After one week, /k/ sound showed marked improvement in all subjects. Significant distortion of /n/ sound was recorded (p<0.008) for up to 2 months. No significant speech distortions were recorded after 3 months (p>0.008). Conclusions:A marked distortion of /t/, /d/, /k/ and /n/ consonant sounds were observed in patients during the initial wearing of Hawley retainer. Patient needs to be well informed of the changes and encouraged for constant wearing. With good cooperation, speech will be adapted to normal pattern within 3 months.

The aim of this systematic review was to compare the therapeutic and adverse effects of lingual and labial orthodontic fixed appliances from clinical trials on human patients in an evidence-based manner. Randomized and prospective non-randomized clinical trials comparing lingual and labial appliances were included. Risk of bias within and across studies was assessed using the Cochrane tool and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Random-effects metaanalyses were conducted, followed by subgroup and sensitivity analyses. Six electronic databases were searched from inception to July 2015, without limitations. A total of 13 papers pertaining to 11 clinical trials were included with a total of 407 (34% male/66% female) patients. Compared with labial appliances, lingual appliances were associated with increased overall oral discomfort, increased speech impediment (measured using auditory analysis), worse speech performance assessed by laypersons, increased eating difficulty, and decreased intermolar width. On the other hand, lingual appliances were associated with increased intercanine width and significantly decreased anchorage loss of the maxillary first molar during space closure. Based on existing trials, there is insufficient evidence to make robust recommendations for lingual fixed orthodontic appliances regarding their therapeutic or adverse effects, as the quality of evidence was low.
