12. Early Loss And Rampant Caries As Factors Influencing Development Of Malocclusion

Question 1

12. Early Loss And Rampant Caries As Factors Influencing Malocclusion

Role deciduous teeth play in maintaining dental arch integrity and occlusal balance

Answer 1

• Functional units for chewing
• “Space savers” for permanent teeth

Question 2

12. Early Loss And Rampant Caries As Factors Influencing Malocclusion

How premature loss of deciduous teeth impacts the dental arch and occlusion

Answer 2

• Can lead to various malocclusions
• E.g -Premature extraction of second primary molar=>
• Mesial drift of permanent first molar( blocks eruption pathway of second premolar)
• Results in buccal or lingual displacement of erupting premolar=>malocclusion

Question 3

12. Early Loss And Rampant Caries As Factors Influencing Malocclusion

Consequences of premature loss of primamry canines

Answer 3

• Closure of space primarily by distal drift of incisors
• If the loss occurs only on one side=>asymmetry in occlusion and a tendency toward crowding
• The contiguous teeth may tilt and the opposing teeth may overerupt

Question 4

12. Early Loss And Rampant Caries As Factors Influencing Malocclusion

How early loss of primary teeth affects eruption of permanent successors

Answer 4

• may lead to early eruption of permanent successor
• obstacles such as bony crypts or mucosal barriers can impede eruption pathway of permanent teeth

Question 5

12. Early Loss And Rampant Caries As Factors Influencing Malocclusion

Measures necessary to prevent space loss after premature loss of primary teeth

Answer 5

• Space maintainers=>
• Especially in cases of arch length deficiency or overjet problems

Question 6

12. Early Loss And Rampant Caries As Factors Influencing Malocclusion

How early loss of primary teeth impacts arch length and tooth alignment

Answer 6

• Can lead to arch length shortening on affected side
• Tipping of adjacent teeth
• Overeruption of opposing teeth

Question 7

12. Early Loss And Rampant Caries As Factors Influencing Malocclusion

How dental caries contributes to malocclusion

Answer 7

• Can lead to premature loss of deciduous or permanent teeth
• Results in drifting of adjacent teeth
• Abnormal axial inclination
• Overeruption and bone loss
• Changes disrupt the alignment and occlusion of teeth

Question 8

12. Early Loss And Rampant Caries As Factors Influencing Malocclusion

Role of untreated proximal caries in altering dental arch dimensions

Answer 8

• Can result in actual loss of arch length due to tooth loss
• Leads to drifting of adjacent teeth and further malocclusion

Question 9

12. Early Loss And Rampant Caries As Factors Influencing Malocclusion

How dental caries on occlusal or incisal surfaces affects the vertical dimension of occlusion

Answer 9

• Decrease in vertical dimension of occlusion
• Results in overeruption of opposing teeth=>disrupts balance of occlusion

Question 10

12. Early Loss And Rampant Caries As Factors Influencing Malocclusion

Issues that can arise from improper restorations in relation to malocclusion

Answer 10

• Broken contacts or restorations
• Poor proximal contacts => food packing and periodontal breakdown
• Lack of anatomic detail allowing supra-eruption
• Under or overcontoured proximal restorations => drifting or reduction of space for succedaneous teeth

Question 11

12. Early Loss And Rampant Caries As Factors Influencing Malocclusion

How overcontoured proximal restorations impact succedaneous teeth

Answer 11

• Can bulge into space intended for succedaneous teeth
• Reduces available space for their eruption
• Can lead to crowding and malocclusion
