Molar Incisor Hypomineralization

Brief summary

Molar Incisor Hypomineralization (MIH) is enamel hypomineralization defined as qualitative defects caused by disruptions in either the calcification or maturation phases of amelogenesis affecting one or more first permanent molars (FPMs) and permanent incisors.

Detailed description

Conventional treatment for such defects necessitates additional removal of the complete tooth structure to receive full crowns that cause more biologically harmful consequences like postoperative hypersensitivity and aggressive tooth structure loss. To fulfill the biological criteria for tooth preparation, conservatism is the major notion and goal that prosthodontists strive to achieve. Nowadays, minimally invasive techniques are frequently employed to support this idea. To meet the growing need for conservative and attractive tooth restorations, overlay ceramic restorations (covering all cusps) are becoming more necessary. These restorations show satisfactory mechanics, restoring function, and esthetic with preserving tooth structure Since all materials used to treat such cases, have distinct chemical compositions, they have different properties that affect their clinical outcome. Therefore, it is essential to compare them clinically because any restoration's clinical outcome affects its long-term success. According to the null hypothesis, different materials would not significantly affect the clinical result of ceramic overlay restorations. Patients in all groups will receive a minimally invasive restoration with high esthetic advantages (Protection of the weak cusps and elimination of carious lesions with an esthetic way out) and long-term success of their MIH affected young permanent molars (either IPS e.max CAD, Direct nanohybrid flowable composite or VITA Suprinity PC-Glass ceramic (zirconia) that require minimal preparation depends on the type of restoration will receive.

Interventions

OTHERrestoring the MIH affected young permanent molars using Direct nanohybrid flowable composite

(Shofu)is a bioactive flowable nano-hybrid restorative with a newly developed patented nanofiller. It is indicated for all classes including occlusal and cusp. It has all of the Giomer Technology attributes, anti-bacterial, acid neutralization, and fluoride release and recharge, with improved handling and effortless polishing, and maintains a long-lasting shine. Beautifil Flow Plus X has the strength, durability, and aesthetics of a hybrid composite.

OTHERrestoring the MIH affected young permanent molars using IPS e.max CAD

glass-ceramic-based restorations still offer the best translucency and esthetic qualities. The novel generation of lithium disilicate-based materials as IPS e.max CAD provides standard thickness and quick fabrication. Moreover, the adhesive technique used with this restoration type significantly raises its mechanical properties.
