Protraction of a second molar into the gap left by a missing first molar is an option, although it is challenging to maintain root parallelism during mesial migration due to the thick and dense cortical bone. This study was carried out to make an attempt to evaluate whether molar protraction in subjects with missing mandibular first molar and knife edge ridges is possible or not using ridge split procedure (expansion).The sample consisted of 12 subjects with missing mandibular first molar and knife edge ridges. All pre-treatment records were taken, after initial leveling and alignment ridge split procedure was performed and molar protraction was carried out using mini implants. Data was collected at a fixed interval of every six weeks. Statistical analysis using Repeated-measures ANOVA and Paired t test were done for evaluation of the rate of molar protraction and mesial molar tipping 0.12mm per week and 0.9 mm per six weeks was the rate of molar protraction that was accomplished. The mean edentulous space decreased from pre protraction to third visit significantly with a p value of ≤ 0.001.There is mesial tipping of molar post protraction with a P value of 0.148 which is statistically non-significant. On an average duration for molar protraction was 8.4 months.Ridge split made molar protraction possible in subjects with missing mandibular molar and knife edge ridges and enhanced the rate of tooth movement. The absolute anterior dental anchorage for the desired orthodontic movement was achieved by utilisation of mini implants.

“…1 Some treatment options that are available after extraction of molar include implant, prosthese, and space closure using orthodontic devices. 2 The treatment of choice in treating edentulous area should be the least invasive option that complies the expected esthetic and functional objectives. 3 In orthodontic treatment option, the protraction of second molars to the edentulous area becomes the preferred choice, with the support of bones and good oral hygiene.…”

“…In the case of molar protraction, placing the power arm on the buccal tube can help to place a force close to the C res so that a bodily movement can be obtained. 2,8 Sliding jigs are commonly used to apply intra or intermaxillary forces in the procedure of tooth distalization or mesalization. Sliding jigs have two main functions; retraction of individual teeth and molar distalization.…”

Objective: When a first molar is lost, orthodontic replacement with second and third molars would be an excellent treatment option. There are some side effects that tend to occur during molar protraction, such as mesial tipping of molar that could increase the time required to correct. These side effects can be avoided by understanding the biomechanical variables affecting molar protraction. The author tries to present the modification of sliding jigs, instead of the power arm function, with additional of lingual force, for molar protraction. Methods: This case report describes the management of a 23-yearsold woman who was missing left mandibular first molar, had class III skeletal profile, and anterior crossbite. After anterior crossbite correction, the left mandibular first molar extraction spaces were closed by protraction of the second and third molars. Mesial tipping was detected in the early protraction phase when using conventional method. Consequently, uprighting procedure was done and protraction was continued using reciprocal force generated by two sliding jigs and lingual buttons to achieve bodily movement of tooth. Results: The result was excellent, the space was closed without tipping and rotation. Conclusion:The presented article provides an alternative mechanic for molar protraction using sliding jigs and how it can be designed to achieve predictable result.
