1. General information
• The presentation deals with the necessity and methods of incisor adjustment in horses in the context of dental treatment.
• It is emphasised that almost every dental treatment in horses requires an adjustment of the incisors, especially when feeding unnatural feed.

2. Important studies and publications
• Schröter (2017): Investigation of the occlusal surface angles of incisors and molars in horses.
• Dixon (2002): Influence of feed structure on occlusal surface angles.
• English (2018): Anatomy of equine incisors, particularly the thickness of subocclusal dentin.

3. Adaptation of the incisors
• Adaptation of the incisors is important to correct malocclusions and promote the health of the temporomandibular joint.
• Adjustment of the incisors is important to allow equal loading of all molars
• Adjustment should be made in relation to the molars.
• Different methods of adjustment include grinding, cutting and milling.

4. Practical guidelines
• The adjustment should take into account the angle to the temporomandibular joint or lower.
• The thickness of the secondary dentin is a limiting factor.
• Empirical experience shows that the retraction of the gingiva between the incisors is a good indicator of the adaptation possibilities.

5. Examples
• The document contains several case studies illustrating the necessity and results of incisor adjustment in different horses.

6. Conclusions
• Incisor adjustment is necessary and should be performed carefully.
• Gum retraction and the colour of the secondary dentin are good guidelines for adjustment. o Scientific studies support the necessity of adjustment.
