Descrizione dettagliata
This prospective clinical study evaluates the changes in occlusal force distribution in patients with maxillary transverse deficiency undergoing piezocision-assisted rapid maxillary expansion (RME).
Participants aged 14-22 years with permanent dentition requiring rapid maxillary expansion are allocated into two age-based study groups:
Group I (Adolescents): Patients aged 14-16 years. Group II (Young Adults): Patients aged 18-22 years. All participants undergo piezocision-assisted RME. Under local anesthesia, selective vertical micro-incisions are made interproximally on the buccal alveolar bone distal to the canines, first premolars, and second premolars. Corticotomy cuts to a depth of 3 mm into cortical bone are performed using a piezoelectric surgical device. A bonded tooth-borne Hyrax expander is then cemented and activated two quarters per day (0.5 mm of expansion per day) for 11 days. The expander is maintained as a passive retainer for 3 months to allow stabilization and midpalatal suture remodeling. Primary outcomes evaluate percentage changes in occlusal force distribution at maximum intercuspation across dental arch segments (Anterior vs. Posterior and Right vs. Left), as well as occlusion time and disclusion time during excursive movements, using quantitative digital occlusal force analysis(T-Scan III, Tekscan Inc., Norwood, MA, USA)). Secondary outcomes assess patient-reported pain and discomfort levels at defined time intervals.

Sperimentale: Group I: Adolescents
Adolescent patients aged 14-16 years with maxillary transverse deficiency receiving piezocision-assisted rapid maxillary expansion (RME).

Under local anesthesia using Articaine with 1:100,000 Epinephrine, selective vertical micro-incisions are made interproximally through the attached gingiva to the maximum extent possible using a 15c scalpel blade via a flapless technique, extending through the periosteum to reach the alveolar bone.
Corticotomy cuts are performed using a piezoelectric surgical device with a BS1 Slim II tip to a depth of 3 mm into cortical bone, initiated 2 mm apical to alveolar crest and safely positioned between adjacent tooth roots to avoid iatrogenic injury.
Immediately following surgery, activation of a bonded tooth-borne Hyrax expander commences at a rate of one activation (quarter turn) twice daily (0.5 mm/day) for 11 days, followed by a 3-month passive retention phase for suture remodeling.
Altri nomi:
Quantitative digital measurement of occlusal force parameters using the T-Scan III system (Tekscan, Inc., Norwood, MA, USA) with HD sensors.
Static parameters assessed at Maximum Intercuspation (MIC) include: (1) percentage of force distribution between anterior and posterior teeth, and (2) percentage of force symmetry between right and left arch sides.
Dynamic parameters assessed include: (1) Occlusion Time (OT) measured from initial tooth contact to MIC, and (2) Disclusion Time (DT) recorded during right, left, and protrusive excursive movements.
