1-Consequences of tooth loss

• Mesial tipping and rotations of distal molars

http://pocketdentistry.com/18-special-considerations-in-treatment-for-adults/

Loss of a lower molar can lead to tipping and drifting of adjacent teeth, poor interproximal contacts, poor gingival contour, reduced interradicular bone, and supra-eruption of opposed teeth. Note the loss of alveolar bone in the area where a

mandibular first molar was extracted

1a-Consequences of tooth loss

• Distal tipping and rotations of mesial teeth

1b-Consequences of tooth loss

• Eruption of opposing tooth in edentulous space

LE MAY J-https://www.orthodontisteenligne.com/en/ortho-101-en/adult-orthodontics-4/

Loss of posterior teeth in an adult. On one side (A), the loss of a lower molar allowed the other molars to tip forward. On each side (A and B), the upper molars migrate toward the space below (extrusion).


1c-Consequences of tooth loss

Gingival tissues become folded, and pockets form in the area


1d-Consequences of tooth loss

This photo shows a lower ridge that has lost 60% of its width following an extraction and normal healing. The black arrows indicate where bone is

located (compare the width to the adjacent molar). The red arrows indicate the normal width that should be there.

1s- Managing the orthodontic-restorative patient

Early Tooth Loss and Space Maintenance Space regaining: Molar Uprighting and Distalization

Early tooth loss can be a result of traumatic avulsion or extraction of carious or infected teeth, Premature loss of primary teeth can result in a loss of arch length and have a negative effect on

occlusion and alignment, often increasing the need for orthodontic treatment.


2-Multi-disciplinary approach for space management of Microdontia

- A minimal reduction was needed for lateral incisors. - Veneers cemented on lateral incisors. - Definitive composite restorations after finishing and polishing procedures.

2c-Anterior Space Management

Additional orthodontic treatment is initiated to improve the dental midline and evenly distribute the space around the microdontic lateral incisors




3-Implant site preparation

Move the roots from implant site, To create space priorimplant placement, the roots of the adjacent teeth should be upright and parallel

Orthodontic extrusion

• Orthodontic extrusion uses “orthodontic forces”.

• The PDL including alveolar bone follows the extruding tooth

• Rapid extrusion uses heavier forces, more frequent activations and results in extruding the tooth beyond the PDL – lengthen clinical crown
