This video includes all of the following videos from Course09 Crown lengthening & Extrusion.

[#1 Understanding the Dentogingival Complex]
Gingivitis and periodontitis are caused by various reasons, but it is necessary to correctly diagnose why inflammation occurs and take appropriate measures.
He presented cases with different causes of gingivitis, and explained the initial treatment and cases caused by occlusion after understanding the Dentogingival Complex.

[#2 Inflammation Control]
If the gingiva bleeds due to gingivitis or periodontitis, or if the gingiva is accidentally injured and bleeds during the procedure, bonding operations and restorative procedures cannot be performed properly.
The use of a rubber dam prevents blood from entering the surgical field and eliminates the risk of damaging healthy gingiva.
In the video of the actual procedure, he explains the advantages in detail and also discusses a case in which a rubber dam cannot be applied due to a residual root condition.

[#3 Facing Hemostasis]
Crown lengthening procedure can be broadly divided into two methods: lateral root shifting and gingival excision, but how should we diagnose and select the right one?
From a review of the GingivalComplex, he explains the diagnostic criteria based on a case using the Widman Improved Method.

[#4 Diagnostic Criteria]
This is a review of the second molar cases mentioned in #3 and the diagnostic criteria.
He also goes into depth on the importance of securing the ferrule to obtain a good prognosis.

[#5 Tooth Extrusion]
In #5, you can see the first crown lengthening and tooth extrusion case that Dr. Uchiyama performed.
Dr. Uchiyama invented the device used in toothextrusion for this case, and also did the wax-up and casting himself.
This case was done in his second year of clinical practice, so you can learn not only the content but also how to deal with patients and dental care as a dentist.

[#6 The case - Short root]
What should be done if the root of the tooth to be treated with tooth extrusion is short?
In this article, he explains a case in which crown lengthening and tooth extrusion were actually performed on a maxillary left first premolar with a short tooth root.

[#7 Suture and Final]
Finally, from suturing to retention, removal, and Final. He also discusses the diagnostic and selection criteria from various requirements not for individual teeth but for the whole jaw. You will learn how to actually remove and retain devices and what to focus on, which cannot be learned only from the knowledge of retention intervals and indications.

[#8 Diagnosis in the aesthetic field]
This is crown lengthening and tooth extrusion with multiple teeth in the maxillary anterior teeth. You will learn not only how to secure the ferrule, but also what to focus on in the esthetic field, such as the gingival line, and how to deal with it.

[#9 Crown Length Rings and Provisional Restorations]
This is crown lengthening and tooth extrusion with multiple teeth in the maxillary anterior teeth. You will learn not only how to secure the ferrule, but also what to focus on in the esthetic field, such as the gingival line, and how to deal with it.

[#10 Provisional Restorations and Prosthetics]
Learn what to look for in provisional restorations and how to match the color tone and form of laminate veneers, prosthetics, and natural teeth.

[#11 Occlusion and Crown Lengthening]
This course is about crown lengthening for difficult cases with occlusal problems.
You will learn about the treatment sequence, methods, and diagnostic criteria. It is a review of the past and focuses on provisional restorations. Please take a look!

[#12 All-round case]
Learn about perio, occlusion, ferrule securement, how to approach cases with a variety of problems and provisional restorations.
