1. Introduction Applied anatomy of maxilla Pterygoid area Applied anatomy of mandible. Retromolar area Summary References
2. Normal vs abnormal anatomy from tooth loss generates a compromised repaired structure both in function and form. Goal will be to develop a view of surgical anatomy as it relates to surgical procedures
3. Hollow and cuboid shaped Paired bone with pyramidal base facing medially,separted by nasal fossa. Septum in center,bordered inferiorly ,bilaterally by oral cavity.
4. Hollow maxilla is covered by a 3 layered mucoperiosteum. Color –purple –red Elastic consistency Thin ,yellow and friable-smokers
5. Unrepairable membrane perforation. Sinus and posterior teeth. Pneumatization of sinus.
6. Most common complication. Repair of relatively small (5-10 mm) tears is commonly done using fast resorbing collagen membranes and/or by allowing the sinus membrane to overlap on itself. A technique using a cross-linked type I collagen membrane for predictable repair of large perforations (> 10 mm) as well as for circumstances in which no membrane is found is described. Implant Dent 2008;17:24–31
7. Sinus expansion and faulty Rx planning
8. • In cases of resorbed maxilla,sinus is at crest of RAR • Bone level may approximate level of floor of nasal cavity.
9. Inferior turbinate is 5mm-9mm above nasal floor. During sinus lift-graft should be kept at least 2mm to avoid ostium blockage.
10. Accessory ostia-30- 40 percent cases Nasal endoscopy to be safe.
11. • Incisive canal ,found adjacent to nasal septum ,8-18 mm behind anterior aspect of floor of nasal fossa. • May be at level of crest in resorbed ridges
12. May be chosen by surgeons for implants Goal-engage pterygoid process without bone augmentation- creating abutment for FPD.
13. Caution-pterygoid fossa lying superiorly is avoided_severe hemorrhage may occur. Ptergomaxillary butress –an area of increased bone density and volume is responsible for transmitting masticatory forces.
14. Anatomic features of dentulous and edentulous mandible. The muscles, innervation are of prime importance
15. • Severely resorbed mandible-internal oblique line at level with crest of RAR. • Genial tubercles superior to crestal bone,and exposed neurovascular bundle.
16. Implant position is changed as it relates to axis of bone resorbs. In anterior mandible,onlay bone grafts in 2 stage,or,one stage may be done.
17. Tremendous variation seen in mental nerve as it exits the mental foramen.
18. Retraction of alveolar nerve. 3 branches of mental nerve
19. Some clinicians consider Mental nerve to be in Halfway between inferior border of mandible and alveolar ridge. Generally,it is located slightly inferior toward the border of mandible,although it can be found 1/3rd inferiorly to mandible than superiorly.
20. Relation of inferior alveolar canal to 1st 2nd and 3rd molars.
21. Injury to IAN that remains in atrophied bone and does not innervate soft tissues is of less consequence. Nerves in bone,when in contact with implant ,account for tenderness,even though implant is rigid and healthy.
22. Lingual nerve-Improper flap reflection may cause an injury. Ipsilateral paresthesia Anaesthesia of innervated mucosa. Loss of taste. reduction of salivary secretion.
23. MYLOHYOID Muscle ◦ Structures above mylohyoid-intraoral swelling ◦ Sublingual space infection. ◦ Below mylohyoid – ◦ Submandibular space infection.-extraoral swelling
24. ◦ Attaches to genial tubercles. ◦ Should not be completely detached - airway obstruction.
25. Bounds pterygomandibular space medially,near insertion at medial surface of mandible. Infection can spread to paraphayngeal space-into mediastinum.
26. ◦ Fibres insert into condyle, TMJ disk. ◦ Because of angulation of lateral pterygoid muscle,mandibular flexure may be caused –causing alteration in mandibular arch width,pain in patients with sub-periosteal implants
27. Insertion is into coronoid process of mandible. Surgical exposure ,medially in ramus may injure tendon of temporalis-while harvesting bone from external oblique ridge,or placing incision for subperiosteal implants.
28. Complete reflection of mentalis muscles for purpose of extension of subperiosteal implant or symphyseal intraoral graft may result in witch’s chin. If muscle is completely detached to expose symphysis,then elastic bandage is applied externally to chin for 4 days to help in reattachment of muscle.
29. Some patients wearing lower sub-periosteal implants c/o episodic swelling and pain at the site of origin of heavymastication or bruxism. Myositis of detached muscle may cause it.
30. Massetric space infection may result. during surgery to expose bone for ramus extension needed for lateral support of sub-periosteal implant.
31. Anatomic sites for dental implants. Orthodontic anchorage can be derived. Healthy teeth can be moved upto 15 mm within alveolar process without compromising position of remaining dentition.
32. Implant placement is 5 mm distal to 3rd molar. Engage between cortical bone ,between mandibular retromolar area and ascending mandibular ramus. Prevent entry into mandibular canal.
33. Surgical anatomy of maxilla and mandible provide foundation required for safe insertion of dental implants. The anatomy is requisite to understanding of complications that may occur during surgery ,like injury to blood vessels or nerves,as well as post – op complication such as infection. This information is important for operator, to deal with confidence and to avoid complications.
