The Crown Lengthening Surgical techniques are multiples and are dependent on the Initial Situation and the Objective to achieve.

These procedures have in general an Esthetic, a Biologic and Bio-mechanical objectives and could be a combination of them in Complex Cases.

Gingival Smile can result from different abnormalities, and is often a Combination of several ones.

Since the Gingival Smile is of multifactorial origin, it cannot be until Esthetic and Etiological Diagnosis have been established.

Crown Lengthening Procedure, is a Surgical treatment modality to achieve the apically repositioning of the Biological Width, to increase the height of the teeth, create the normal teeth proportion, harmonize the Gingival contours, treat the Gingival Smile, reestablish a healthy tooth structure on Broken teeth.

Establishing an Adequate Classification and a Correct Diagnosis, would definitely help the clinician to choose the most appropriate Surgical Procedure to prevent any recurrence of the Soft Tissue over the teeth and achieve an optimal esthetic Result.

The utilization of CBCT, Digital Dental Smile and CAD CAM Digital Workflow, have change dramatically establishing a more precise diagnosis and using of a new Type of Surgical Guide to perform the surgery in a more precise and minimal way.

The new Biological Width will take about 6 months to heal, histologically which suggest to wait this minimum time to restore any teeth in the esthetic zone.

Therefore, restoring the normal biological width is the principal objective at the end of each surgical session to prevent recurrence of the excess of soft tissue and esthetic complications.

The objective of this presentation is to establish a precise diagnosis for a well-planned surgical strategy using the conventional or digital approach with a surgical guide, in order to give a satisfactory smile to the patient as defined in treatment plan.
