The loss of the first permanent molar in a child can lead to changes in dental arches that can be traced throughout the child’s life. Unless corrective measures are taken, these changes include diminished local function, drifting of teeth, and continued eruption of opposing teeth. The second molars, even if unerupted, start to drift mesially after the loss of the first permanent molar, causing a greater degree of forward bodily movement especially in 8-12 years old children. Unless corrective measures are taken, in older children, if the loss occurs after the eruption of the second permanent molar, more exaggerated mesial tipping of the second molar can be the expected outcome. Although the premolars undergo the greatest amount of distal drifting, all teeth anterior to the space, including central and lateral on the side where the loss occurred, may show evidence of movement. Contact open and the premolars, in particular, rotate as they fall distally. There is a tendency for maxillary premolars to move distally in unison, whereas those in the lower arch move separately. When the maxillary first permanent molar loses its opponent, it erupts at a faster rate than adjacent teeth.

Study Notes
Loss of First Permanent Molar
- The loss of first permanent molar in a child can lead to changes in dental arches that can be traced throughout the child's life.
- A carious lesion may develop rapidly in the first permanent molar and progress from an incipient lesion to pulp exposure in a 6-month period.
- The first permanent molar is the most important unit of mastication and essential in the development of desirable occlusion.
Consequences of Loss of First Permanent Molar
- Diminished local function
- Drifting of teeth
- Continued eruption of opposing teeth
- The second molars, even if unerupted, start to drift mesially after the loss of the first permanent molar.
- In older children, if the loss occurs after the eruption of the second permanent molar, more exaggerated mesial tipping of the second molar can be expected.
- Although the premolars undergo the greatest amount of distal drifting, all teeth anterior to the space, including central and lateral on the side when the loss occurred, may show evidence of movement.
- Contact opens and the premolars, in particular, rotate as they fall distally.
- There is a tendency for the maxillary premolar to move distally in unison, whereas those in the lower arch move separately.
- When the maxillary first permanent molar loses its opponent, it erupts at a faster rate than adjacent teeth.
Management of Loss of First Permanent Molar
- The treatment of patients with the loss of the first permanent molar must be approached on an individual basis.
- If the first permanent molar is removed several years before the eruption of the second permanent molar, there is an excellent chance that the second molar will erupt in an acceptable position.
- When the first permanent molar is lost after the eruption of the second permanent molar, orthodontic evaluation is indicated.
- The following steps are indicated:
- Is a child in need of corrective treatment other than in the first permanent molar area?
- Should the space be maintained for a replacement prosthesis?
- Should the second molar be moved forward into the area formerly occupied by the first molar?
- The latter choice is more satisfactory, even though there will be a difference in the number of molars in the opposing arch.
- A third molar can often be removed to compensate for the difference.
Types of Appliances to be Used
- Removable acrylic partial denture has been used in the arch after the loss of multiple teeth.
- Passive lingual arch or Nance appliance
- Transpalatal-bar appliance
- It is occasionally necessary to recommend extraction of all primary teeth in a preschool child and wear a complete denture before the eruption of permanent teeth.
Premature Loss of First Primary Molar
- The effect of premature loss of the first primary molar in both arches is mostly dependent on the state of eruption of the first permanent molar.
- If the primary first molar is lost during the primary dentition (ages 3-5), there should be little or no space loss associated with the mesial movement of the second primary molar.
- If the primary first molar is lost as the first permanent molar erupts (ages 5-7), this will cause:
- A strong force exerted that pushes the second primary molar forward into the first primary molar space.
- A loss of posterior arch length within the quadrant that can lead to crowding as the canines and premolars erupt in later stages.
- Mandibular arch length may be further compromised by distal and lingual shifting of anterior teeth toward the side of the first primary tooth loss.
Management of Premature Loss of First Primary Molar
- The use of a space maintainer is desirable to stabilize the second primary molar and canine positioning.
- For unilateral loss of primary first molar, a unilateral band or crown and loop is usually the appliance of choice.
- For bilateral loss of primary first molar and the second primary molar retained in the lower arch, two separate unilateral loop appliances are indicated until the first permanent molar and incisor eruption is complete.
Premature Loss of Second Primary Molar
- The effect of loss of the second primary molar depends on the state of eruption of the first permanent molar.
- If a second primary molar is lost in a child (ages 2-5), no space loss should occur while the first permanent molar is in the basal bone.
- If the first permanent molar erupts, considerable loss in arch length can occur if no second primary molar is present as an eruptive guide.
- If the loss of the second primary molar occurs after the first permanent molar has fully erupted and normal cuspal interdigitation has been established, the degree of space loss should be less dramatic than earlier during molar transition.
Management of Premature Loss of Second Primary Molar
- If the loss occurs just before the eruption of the first permanent molar, a space maintainer to guide the positioning of the first permanent molar into normal occlusion is desirable.
- The appliance of choice is a distal shoe for both maxillary and mandibular arches.
- If the first permanent molar is erupting, the classic bilateral mixed-dentition space maintainer in the mandibular arch is a passive lingual arch with bands fitted to the first permanent molar.
- In the maxillary arch, a bilateral mixed-dentition space maintainer to stabilize molar position bilaterally is a Nance appliance.
