Study Notes
Patient Evaluation and Diagnosis
- Age: Younger patients tend to adapt to dentures more easily
-
Physiological Conditions:
- Endocrine glands and sex hormones affect bone and calcium metabolism.
- Menopause can negatively impact alveolar ridges.
-
Sex:
- Men and women have different esthetic demands.
- Women may prioritize appearance over function.
- Sex hormones influence supporting structures.
-
Occupation:
- Consider design and impression techniques based on the patient's profession.
- Appearance and retention are crucial for people with frequent interaction with others.
- Public speakers and singers require careful consideration of palatal shape and thickness for proper phonetics.
- Wind instrument players may need anterior teeth modifications.
-
General Health:
- Chronic, debilitating diseases can affect denture success.
- Oral manifestations may include pain, burning sensations, and tissue changes.
- Conditions like anemia, diabetes, syphilis, tuberculosis, blood dyscrasias, and neoplasms can impact oral health.
- Caution is needed for patients who have undergone radiation therapy.
-
Arthritis:
- Limited mandibular movement during impression making and jaw relation registration.
- Frequent occlusal corrections may be necessary.
-
Diabetes:
- Patient should be under medical control.
- Maximum physiologic compatibility between the denture base and supporting tissues is crucial.
- Increased susceptibility to infections.
- Removal of occlusal interferences.
- Instruction on eating habits and oral hygiene.
- Frequent denture evaluations.
-
Bell's Palsy:
- Retention may be challenging, adhesives may be necessary.
- Tissue support can be problematic due to paralyzed musculature.
- Education on mastication and oral hygiene.
-
Parkinson's Disease:
- Sedatives may be needed for patient control during denture fabrication.
- Retention can be difficult.
- Denture removal when not in use.
-
Anemia:
- Medical care is needed.
- Efficient dentures are important for dietary needs.
- Small occlusal table with maximum supporting area to minimize tissue stimulation.
- Good oral hygiene.
-
Radiation:
- Avoid abrasion or irritation to tissues.
- Open lesions may indicate osteonecrosis.
- Dentures should ideally be avoided over irradiated tissue, but if necessary, they should not be used until at least two years after radiotherapy.
-
Acromegaly:
- Regular prosthesis checks for adjustments due to potential growth of the mandible and maxilla.
-
Denture History:
- Information on past denture wearing experience is critical.
-
Teeth Loss History:
- Difficult extractions may warrant radiographic examination.
- The order of tooth loss impacts denture success.
-
Patient's Attitude Towards Appearance:
- Requires extra time and care.
- Pre-extraction records are helpful.
- Consider customization of teeth and gingiva.
-
Patient's Mental Attitude Towards Dentures:
- Patients come with varying levels of experience and attitudes towards dentures.
- Both extreme optimism and pessimism can be detrimental.
- Classified into four categories:
- Class I (Philosophical): No prior denture experience, optimistic, and generally well-balanced.
- Class II (Exacting): Unsatisfied with previous dentures, demanding, and may seek guarantees.
- Class III (Hysterical): Previous denture failure, discouraged, highly demanding, and desire near- perfect teeth.
- Class IV (Indifferent): Unconcerned about appearance or function, and may not be motivated to adjust to dentures.
- Additional categorization:
- Cooperative:
- Apprehensive:
- Uncooperative:
-
Examination:
- Old Dentures: Analyze the wear, resorption, and denture stability.
-
Visual Examination of Oral Tissues:
- Assess alveolar mucosa, including normal, atrophic, and hypertrophic conditions.
- Observe irritated mucosa.
- Arch Form: Analyze the shape of the dental arch, which can influence retention and stability (Square > Ovoid > Tapering).
- Arch Size: Larger jaws are more favorable for retention and stability.
-
Vault Form:
- Flat: Good vertical support, but weak against lateral shifts.
- High or 'V' shaped: Resists lateral shifts, but prone to vertical displacement.
- Rounded or 'U' shaped: Most favorable.
-
Ridge Relation:
- Class I (Normal): Favorable stress distribution and esthetics.
- Class II (Retrusive): Requires careful occlusion registration. TMJ issues may be present.
- Class III (Protrusive): Crossbite relationships.
- Depth of Sulci: Shallow and broad sulci require careful impression technique for peripheral seal.
-
Physical Form:
- Favorable Contours: Minor difficulties can be addressed with mechanical relief.
- Unfavorable Contours: Surgery might be necessary.
-
Tuberosities:
- Large tuberosities provide good support and retention.
- Undercuts should be corrected surgically.
- Extremely long tuberosities can interfere with interarch space.
- Assess coronoid process-tuberosity relationship.
- Undercuts along the buccal aspect of both ridges anterior to tuberosity.
- Undercuts on the lingual side of the lower.
- Tori: Palatal torus, Mandibular torus.
- Frenum Attachment: Significant if near the ridge crest.
-
Ridge Form:
- Evenness: Smooth and rounded ridges are ideal for retention.
-
Cross-sectional Form:
- Flat: Difficult, but manageable with good tongue position and a wide buccal shelf.
- Knife Edge: Often associated with tapered arches, narrow buccal shelves, and prominent mylohyoid ridges.
-
Throat Form: Related to the post dam area.
- Class I: Large immovable tissue with a low palatal vault and small tuberosities (most favorable).
- Class II: More acute junction.
- Class III: No immovable tissue posteriorly, right angle (least favorable).
-
Tongue Position:
- Normal position is favorable for lingual seal and retention.
- Broad, Flattened: Challenging for impressions.
-
Retruded: Four forms:
- Apex curls downwards, radix elevated.
- Apex curls upwards.
- Apex disappears into the tongue body, square appearance.
- Tongue body depressed.
- Mouth Opening: Large is favorable for impressions, small is unfavorable.
- Lip Size: Long lips present no esthetic challenge, short lips require attention to esthetics.
- Face Form: Square, Tapering, Ovoid
-
Digital Examination:
- Muscular Tone: Loss of tonicity can be observed in the absence of natural teeth or dentures.
-
Resorption: Analyze the degree of bone resorption.
- Average:
- Bulky Ridges:
- Excessive:
- Mylohyoid and Retromylohyoid Form: Favorable outcome when these muscles are distant from the ridge crest.
