Abstract | AIM: In orthodontics, the paradigm is shifting since the introduction of micro-implants as anchorage units. However,
patients’ perceptions and acceptance of micro-implants is not fully understood. The aims of this investigation were to
examine patients’ levels of pain in micro-implant surgery both intra- and post-operatively compared with other orthodontic
procedures, and to investigate their perception and acceptance of this technique.
MATERIALS AND METHOD: Seventy-eight micro-implants (Dentos, Absoanchor® System) were placed in 37 patients
(13 males, 24 females, mean age: 23.5 years) as anchorage units. This study consisted of two parts: (1) Level of pain perceived
by patients undergoing various orthodontic procedures, including separation, initial tooth alignment and micro-implant surgery,
were rated by visual analogue scale corresponding to the level of pain expected and perceived in various procedures, and pain
experienced over a 7-day period post-operatively. (2) Questionnaires concerning the patients’ post-operative perceptions,
functional disturbance and satisfaction with micro-implant treatment were collected one month after micro-implant insertion.
RESULTS: The expected level of pain was signifi cantly higher than that experienced during micro-implant surgery (P <
0.001); in contrast to separation and initial tooth alignment procedures, where the pain level experienced was similar to that
of patients’ expectations (P > 0.05). Post-operative pain experienced following one week decreased continuously from day
1 to day 7 in all procedures. The total area under curve of initial tooth alignment over the 7-day period was signifi cantly
larger than that of separation and micro-implant surgery (P < 0.05). The questionnaire study showed that 94.9 per cent of
patients reported only moderate pain or even less during micro-implant surgery. Satisfaction was expressed by 75.8 per cent
of patients with micro-implant treatment who would consider the treatment again if necessary, and 77.8 per cent of patients
would recommend micro-implants to friends and relatives.
CONCLUSIONS: (1) Subjects signifi cantly over-estimated the pain level of micro-implant surgery (2) The pain perceived
one week post-operatively of micro-implant surgery is lower than that of initial tooth alignment. (3) Micro-implants as
anchorage in orthodontics is highly accepted and welcomed by orthodontic patients as they caused minimal post-operative
discomfort. |
