The objectives were to identify the types of retainer frequently used and to investigate the variations in retention practice. METHODS A total of 97 orthodontists were randomly selected, and a questionnaire consisting of 25 multiple-choice questions sent to them by mail. Upon receiving of t...

Post-orthodontic relapse of lower incisors is a common phenomenon. Sometimes a bonded retainer is fitted to prevent this relapse. In this article, we suggest a handy clinical technique of fitting a lower bonded retainer, which is convenient and easy to carry out.

OBJECTIVES The resin-bonded fixed partial dentures have gained immense popularity in recent years as they are more conservative, esthetic, economic and easily fabricated.

The objective of the study were to compare the effects of different groove lengths and thickness of retainers on retention of maxilla...

Maintaining the treatment results following orthodontic treatment is one of the most important aspects of the entire orthodontic treatment process. The purpose of the present study was to evaluate and compare the uses of Hawley and clear overlay orthodontic retainers relative to changes in overjet, overbite, intermolar width, intercanine width, and arch length measurements. These measurements w...

OBJECTIVE To compare the periodontal health of maxillary and mandibular anterior teeth retained with two types of fixed retainers. MATERIALS AND METHODS A fixed straight retainer (SR) group had 39 subjects, and a fixed wave retainer (WR) group had 35 subjects. Subjects were between the ages of 13 and 22 years and had been in fixed retention for 2 to 4 years. Pocket probing depths, bleeding on...

INTRODUCTION A retainer bonded to the lingual surfaces of the mandibular canines (3-3 retainer) is a widely used type of retention. Our aim in this study was to assess the effectiveness of the 3-3 mandibular lingual stainless steel retainer to prevent relapse of the orthodontic treatment in the mandibular anterior region. METHODS The sample consisted of the dental casts of 235 consecutively t...

METHODS Twenty-six infants with bilateral incomplete cleft lip and cleft palate were included in the study. A preoperative nasal retainer was applied in 5 patients from the time of birth to 2.6-3.5 months before...

BACKGROUND The aim of this prospective clinical study was to compare the mean durability and the failure rates of two types of orthodontic retainers. METHODS Orthodontic patients (142) aged between 14 and 28 years were recruited in this study. The polyethylene woven ribbon (Ribbond, Seattle, WA, USA) retainer was compared with a 0.0175-in flexible spiral wire (Respond, Ormco, Glendora, CA, US...
