- The key anatomic landmarks of the maxilla and mandible impact denture retention, stability, and support. A thorough understanding of these structures is essential for proper denture construction.
- Important maxillary landmarks include the incisive papilla, canine eminences, tuberosities, palatal seal area, and hamular notches. Important mandibular landmarks are the buccal shelf, mylohyoid ridge, retromolar pad, and external oblique line.
- Proper molding of these areas in a denture improves fit and reduces soreness, while inadequate adaptation can lead to pain or displacement of the denture.

ABSTRACT: The loose and unstable lower complete denture is one of the most common problems faced by denture patients with highly resorbed ridge. The management of such highly resorbed ridges has always posed a difficulty to the prosthodontist.Obtaining consistent mandibular denture stability has longbeen a challenge for dental profession. The simplest approach often is to extend the denture base adequately for proper use of all available tisues.To achieve this goal impression of the resorbed mandibular ridge is very important. The objective is to develop a physiologic impression with maximum support of both hard and soft tissues.In such cases, an innovative technique of impressionmaking by using a close fitting tray and anelastomeric impression material tomake a proper impression to achieve maximum retentionand stability.This article describes an impression technique used for highly resorbed mandibular ridge using an all green impression technique, to gain maximum retention andstability

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
2. EDENTULOUS ANATOMY In order to properly construct a denture, one must understand the anatomy and physiology of the edentulous patient. A thorough knowledge of the origins and kinetics of the muscles of mastication, facial expression, tongue and floor of the mouth is essential.
3.
4.
5. Labial frenum Buccal vestibule Buccal frenum Maxilla-Anatomic Landmarks Frenum- are folds of mucous membrane and do not contain significant muscle fibers. High frenum attachments will compromise denture retention and may require surgical excision (frenectomy). Buccal vestibule -when properly filled with the denture flange greatly enhances stability and retention .
6. Incisive papilla Canine eminence Maxilla-Anatomic Landmarks Canine eminance - This prominent bone provides denture support . A square arch prevents a denture from rotating and is thus the best for denture stability . Incisive papilla - Is a pad of fibrous connective tissue overlying the orifice of the nasopalatine canal . Pressure in this area will cause a disruption of blood flow and impingement on the nerve, causing the patient to complain of pain or a burning sensation. The denture should be relieved over this area.
7. Post. Palatal Seal Area Tuberosity Maxilla-Anatomic Landmarks Tuberosity - is an important primary denture support area . It also provides resistance to horizontal movements of the denture. Posterior Palatal Seal Area - Is distal to the junction of the hard and soft palate at the vibrating line .
8. Maxilla-Anatomic Landmarks Rugae Rugae- raised areas of dense connective tissue in the anterior 1/3 of the palate. This area resists anterior displacement of the denture and is a secondary support area. Hamular Notch- this narrow cleft extends from the tuberosity to the pterygoid muscles. The pterygomandibular ligament attaches to the pterygoid hamulus which is a thin curved process at the terminal end of the medial pterygoid plate of the sphenoid bone. The hamular notch is critical to the design of the maxillary denture. Improper molding of this area could lead to soreness and loss of retention. Hamular Notch
9. Coronoid process Maxilla-Anatomic Landmarks Fovea palatina Coronoid process - the patient is allowed to open wide, protrude and go into lateral movements. The width of the distobuccal flange will then be contoured by the anterior border of the coronoid process. Fovea palatina - usually two, slightly posterior to the junction of the hard and soft palates. Minor salivary glands - in the posterior third of the hard palate the tissue is very glandular and displaceable. The impression surface may appear irregular as the glandular secretions will adhere to the impression material. Minor salivary glands
10. Maxilla-Anatomic Landmarks Zygomatico- alveolar crest Zygomatico-alveolar crest - the crest has been likened to the buccal shelf in the mandible as a stress bearing area. However, the mucosal coverage is usually very thin and although the bone is in good position for stress bearing, the mucosa is not considered desirable for this purpose (thin mucosa).
11. Hard palate- consists of the two horizontal palatine processes and appears to resist resorption. For this reason it is a primary support area for the maxillary denture. The configuration of a high palate is not conducive to the stability and support of a denture due to the inclined planes. Midline palatal suture- extends from the incisive papilla to the distal end of the hard palate. The overlying mucosa is tightly attached and thin, relief is usually required to prevent soreness. The underlying bone is dense and often raised forming a torus palatinus. Major palatine foramen- the orifice of the anterior palatine nerve and blood vessels . Relief in this area is usually not required due to the abundant overlying tissues. Maxilla-Anatomic Landmarks Midline palatal suture Major palatine foramen Hard palate

13. Excellent prognosis Good prognosis Poor prognosis Very poor prognosis Denture prognosis based on anatomic findings:
15. Mandible-Anatomic Landmarks Labial frenum - histologically and functionally the same as in the maxilla, mucous membrane without significant muscle fibers. Labial flange space Labial Frenum
16. Mandible-Anatomic Landmarks Labial vestibule Labial vestibule - limited inferiorly by the mentallis muscle, internally by the residual ridge and labially by the lip. Mentalis - elevates the skin of the chin and turns the lower lip outward. dictates the length and thickness of the labial flange extension of the lower denture. MENTALIS MUSCLE Origin – crest of ridge Insertion – chin Action – raises the lower lip
17. Mandible-Anatomic Landmarks Alveolar ridge - is a secondary support area . High rate of resorption when excessive pressure is applied to this area. Buccal frenum - histologically and functionally the same as in the maxilla. Buccal Frenum Buccal Frenum Alveolar Ridge
18. Mandible-Anatomic Landmarks Buccal Shelf - bordered externally by the external oblique line and internally by the slope of the residual ridge. This region is a primary stress bearing area in the mandibular arch . Buccal shelf The buccal shelf is a prime support area because it is parallel to the occlusal plane and the bone is very dense. These two factors make it relatively resistant to resorption .
19.
20.
21. Mandible-Anatomic Landmarks External Oblique Line - a ridge of dense bone from the mental foramen, coursing superiorly and distally to become continuous with the anterior region of the ramus. Is the attachment site of the buccinator muscle and an anatomic guide for the lateral termination of the buccal flange of the mandibular denture . External Oblique Line
22. Mandible-Anatomic Landmarks Mental Foramen - the anterior exit of the mandibular canal and the inferior alveolar nerve. In cases of severe residual ridge resorption, the foramen occupies a more superior position and the denture base must be relieved to prevent nerve compression and pain.
23.
24. Mandibular-Anatomic Landmarks Masseter Groove - the action of the masseter muscle reflects the buccinator muscle in a superior and medial direction . The distobuccal flange of the denture should be contoured to allow freedom for this action otherwise the denture will be displaced or the pt. will experience soreness in this area. Masseter Groove Masseter Groove
25.
26.
27.
28. Geniotubercle(Mental Spines)- present on the anterior surface of the mandible and serve as the attachment sites of the genioglossus and geniohyoid muscles . In pts. with severe ridge resorption the geniotubercles may cause discomfort if they are exposed to the denture base. Mandibular-Anatomic Landmarks Genial Tubercles
29. Lingual frenum - overlies the genioglossus muscle, which takes origin from the superior genial spine Sublingual Folds- formed by the superior surface of the sublingual glands and the ducts of the submandibular glands Mandibular-Anatomic Landmarks Sublingual folds Lingual Frenum
30. Mandibular-Anatomic Landmarks Retromylohyoid space - lies at the distal end of the alveolingual sulcus. Bounded medially by the anterior tonsilar pillar, posteriorly by the retromylohyoid curtain which is formed posteriorly by the superior constrictor muscle, laterally by the mandible and pterygomandibular raphe, anteriorly by the lingual tuberosity of the mandible and inferiorly by the mylohyoid muscle.***The retromylohyoid space is very important for denture stability and retention .
