With new aesthetic dentistry approaches, the "perioral region" also enters the dentist's treatment area. With facial analysis methods, aesthetic planning in the perioral and oral region is supported with laser, BTX, dermal fillers and laminate veneers, full ceramic restorations or zirconium porcelain crowns. The most focused concept in aesthetic dentistry is "smile design". Following the development of laminate veneers and the implementation of bonding techniques, new smiles are created by applying aesthetic rules on lip-gum-tooth morphology along with laser crown lengthening surgery and the content of this concept is the application of botulinum toxins (BTX) and tissue fillers (dermal fillers) to the entire perioral region. It consists of dissemination and expansion with its applications. Within the framework of this approach, in addition to prosthetic procedures, new tissue volumes are created in the peri-oral region and aesthetic-enhancing arrangements are made. Until recently, methods such as dermal fillers and BTX were used by medical aestheticians, dermatologists and plastic surgeons. The developments in dental lasers and the prosthetic work areas of aesthetic dentistry (dental-prosthesis) and its inclusion among routine treatments in dentistry have made it inevitable for dentists to be interested in facial aesthetic treatments. For this reason, the new approach of aesthetic dentistry is to evaluate oral tissues not only with intra-oral (inside the mouth) tissues, but also from a broader perspective within the framework of facial analysis, and also intervene in the perioral region. The physician should support the treatment with laminate veneers, full ceramic restorations or zirconium crowns that he has planned or applied in the oro-facial region, and with some facial analysis methods and aesthetic planning in the perioral and oral region (laser, BTX and dermal fillers). Facial Analysis: It is a study carried out to determine the facial features and plan what to do in the oral and perioral region in this morphological structure, and to determine the tooth morphology appropriate to the facial characteristics for prosthetic procedures. In addition to inspection and cephalometric analysis, standardized portrait, oblique and profile photographs are used. Crown Length Extension: Crown Length Extension (KBU) has become widespread with the development of "aesthetic dentistry" and the establishment of the "smile design" approach. The purpose of KBU in aesthetic dentistry is to vertically reduce the undesirably visible mucosal part that lies below the upper lip laughing line when smiling. In recent years, the use of botulinum toxins has also been introduced to achieve a similar goal. After all these minimal interventions, prosthetic treatment is completed with laminate veneers, full ceramic restorations or zirconium porcelain crowns, which are determined individually according to the face, age, gender and personality, and the full facial rehabilitation is completed in terms of dentistry. Nasolabial Region Download: “Gummy Smile Design” is on its way to become routine with the use of botulinum toxins (BTX) in dentistry, as in other branches of medicine. By using BTX in smile design, the aim is to compensate for the "gummy smile" by paralyzing the area between the nose and lips and masking the gums by hanging the upper lip down. Dermal Filler in the Peri-Oral Region: One of the elements that complete the smile design is lip contours. Recently, dermal filler materials have been used to compensate and restore volume to the lips in the peri-oral region and, more importantly, to compensate for and restore "smoker lines", which we can restore to some extent with prosthetic procedures.
