“…A self-locking spring type that has a similar function to mRS also cannot avoid occlusal interference [ 16 ]. Other methods, such as K loop or bonded NiTi wire, that are mainly placed on the buccal/lingual side of teeth, not on the occlusal surface, should be considered in such cases [ 21 , 22 ].…”

Modifications of Rect-Spring to Enhance the Engagement of Ectopically Entrapped Molars with 2 Case Reports

The Rect-spring appliance, used for the management of ectopically erupting molars, shows weak retention on mesially tilted molars. We present three modifications of the appliance for better engagement and their advantages. We describe cases of two 7-year-old patients with ectopically erupting maxillary first molars with a 2.2 mm and 2.5 mm depth of entrapment, respectively. The modified Rect-spring (mRS) was inserted between the ectopically erupting first molar and adjacent primary second molar, and exerted a distalization force with an interproximal wedging effect at the same time. After 3 months, the ectopically erupting first molars were successfully brought into proper occlusion. No discomfort was reported. The mRS is suitable for various locking cases except for severely tilted molars without requiring any laboratory procedures. We suggest it as the first choice for unlocking the first molars.

“…Nikiforuk defined ectopic eruption as a condition in which the permanent teeth, because of a deficiency of growth in the jaw or segment of the jaw, assume a path of eruption that intercepts a primary tooth, causing its premature loss and producing a consequent malposition of the permanent tooth [ 1 ]. Throughout the literature, the terms ectopic eruption and impaction have been used interchangeably, and this is due to the fact that an ectopically erupting tooth might present with various degrees of impaction [ 2 , 3 , 4 ]. This can be seen in cases where the impaction (failure of eruption) of the first permanent molar takes place at the distal prominence of the second primary molar, and thus studies that have referred to the ectopic eruption as impaction were included.…”

Ectopic permanent molar is a condition in which the permanent tooth deviates from its normal path of eruption. The etiology of this eruption anomaly is multifactorial, with both general and local factors. The principal results suggest that a valid indicator of irreversible consequences is the degree of impaction of the first permanent molar. Self-correction is most common between the ages of 7 and 8, after which help may be required. Accordingly, early management can assist in preventing subsequent potential challenges that could interfere with maintaining a balanced occlusion. Several variables, including the degree of mesial tilting, the level of root resorption, and the condition of the second primary molar, may be crucial in choosing the most effective method of treatment. Interproximal wedging and distal tipping are the two basic therapeutic strategies for ectopic permanent molars. Additionally, the use of fixed or removable appliances might also be required. Delaying treatment until a later stage is not recommended because early diagnosis and treatment are essential for optimal management. This review aims to provide a comprehensive overview of ectopic permanent molars, including their prevalence, etiologic factors, self-correction rates, clinical implications for adjacent teeth, and various treatment techniques, that emphasizes the importance of early detection and intervention in the successful management of ectopic permanent molars. In addition, it highlights the importance of future research into the contributing variables of irreversible ectopic molar outcomes.

“…Due to the application of light force, these thin NiTi wires have fewer side effects and can be used easily and immediately without procedures in the dental laboratory. However, they have rarely been used in pediatric dentistry [6][7][8][9][10].…”

Minor orthodontic treatment using a thin wire with high elasticity can shorten the treatment period and reduce the load on the anchorage by the application of light force. Since it can be applied immediately without a dental laboratory procedure and does not require the patient's cooperation, it can be clinically useful. The cases reported here have led to positive results in short periods of treatment, using only a segmented straight 0.012 inch NiTi wire and flowable resin to address various locations within the oral cavity, such as the anterior teeth, premolars, and molars.
